Improve the "hints" section of the metadata so that each hint can provide
the reference to a value provider.
A value provider defines how a tool can discover the potential values of
a property based on the context. The provider is identifed by a name and
may have an arbitrary number of parameters.
Closes gh-3303
Create a new section in the meta-data called "hints" where users can
provide hints about a given property. The most basic use case for now
is to provide a list of values that a property can have. Each value may
have a description.
This sample JSON provides a basic example for a property called `foo.mode`
that exposes 3 values: "auto", "basic" and "advanced".
```
"hints": [
{
"id": "foo.mode",
"values": [
{
"value": "auto",
"description": "Some smart description."
},
{
"name": "basic"
},
{
"name": "advanced"
}
]
}
]
```
This information can be read by tools (such as IDE) and offer an
auto-completion with the list of values.

Update the embedded launch script to include a `chkconfig` comment. This
solves the "Service doesn't support chkconfig" error when executing
the chkconfig command.
Fixes gh-3115
Update the launch script used in fully executable jars to:
- Include LSB-Header comments
- Source `.conf` files either next to the jar for additional script
configuration
Fixes gh-3243
Update the Maven and Gradle repackage tasks so that the embedded
startup script is no longer included by default. This change is
primarily due to the `cf` command line not currently accepting
the unusual jar format.

Do not rely on the packaging type to figure out what the extension of the
main artifact will be. So far, using `jar` and `war` packaging for `.jar`
and `.war` files worked by chance.
We know retrieve the actual extension as provided by Maven's
`ArtifactHandler`.

- Verify that isReady has been called
- When forking, use a random port for JMX
- Don’t wait for application termination as it introduces a race
condition and verifying that shutdown has been requested is
sufficient

SpringApplicationLifecycle provides basic lifecycle operations on the
current Spring Boot application (that is checking if the application has
fully started and gracefully terminate the app). It can be registered as
an MBean of the platform MBean server if a specific property is set.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.
Such change permits the maven plugin to integrate a classical integration
test scenario where the "start" goal is invoked during the
pre-integration phase and the "stop" goal during the post-integration
phase.
Closes gh-2525
Some of the features of the launch.script were not exposed for users
to be able to control at runtime. It now accepts things like
PID_FOLDER and LOG_FOLDER as environment variables, and also adopts
a clear naming convention where only the inputs are UPPER_CASE.
Previously, the CLI’s dependency management used proprietary Properties
file-based metadata to configure its dependency management. Since
spring-boot-gradle-plugin’s move to using the separate dependency
management plugin the CLI was the only user of this format.
This commit updates the CLI to use Maven boms to configure its
dependency management. By default it uses the spring-boot-dependencies
bom. This configuration can be augmented and overridden using the new
@DependencyManagementBom annotation which replaces @GrabMetadata.

This reverts commit b1c0a7cda4.
The plugin publishing process has moved to a new plugin-based approach
that brings with it some significant limitations:
- There's no staging to allow the promotion of good release builds
- There's no easy way to upload an existing artifact
- There's no control over the published pom.
The risk brought by these limitations, particularly the first, are
too great so we will no be publishing the Boot plugin to the Portal
until they're resolved.
Changing the plugin's ID was a breaking change that would require
users to do some work when they upgrade to Boot 1.3. The ID of the
plugin was changed purely so that it met the Portal's requirements.
Given that the plugin will not be published to the Portal for the
foreseaable future there's no need for us to inflict a breaking change
on people when there will be no benefit.

Update JarWriter to set the entry timestamp for nested jars. The
timestamp is set to same time as the first (non directory) entry in

SpringApplicationLifecycle provides lifecycle operations on the current
Spring Boot application. It can be registered as an MBean of the platform
MBean server if a specific property is set. Besides, the JMX name can
also be customized via a property in case more than one Spring Boot
application is started in the same process.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.
Such change permits the maven plugin to integrate a classical integration

The format is rather unusual.
The time is 16 bits: 5 bits for the hour, 6 bits for the minutes, and 5
bits for the seconds. 5 bits only allows 32 values (0-31) so the number
must be doubled, meaning that the time is only accurate to the nearest
two seconds. Also, the JDK rounds this down by subtracting one. The
doubling and rounding is performed by shifting one place to the left
and masking off the right-most bit respectively.
The date is 16 bits: 7 bits for the year, 4 bits for the month, and 5
bits for the day. The year is from 1980, i.e. the earliest date that
can be represented is 1980-01-01.
See http://mindprod.com/jgloss/zip.html for more details of the format.
Fixes gh-2826
Update the Maven and Gradle plugin to generate fully executable jar
files on Unix like machines. A launcher bash script is added to the
front of the jar file which handles execution.
The default execution script will either launch the application or
handle init.d service operations (start/stop/restart) depending on if
the application is executed directly, or via a symlink to init.d.

Gradle’s plugin portal requires each plugin’s ID to be in a namespace.
Our existing ID, spring-boot, does not meet this requirement. This
commit changes the plugin’s ID to org.springframework.boot.spring-boot.

“gradle”.

Following the move to using the separate dependency management plugin
this test is no longer valid. It should have been removed as part of
2c3c62d7
See gh-2133
This commit replaces Spring Boot's basic dependency management support
with separate dependency management plugin. This has a number of
benefits including:
1. A Maven bom can be used rather than a custom properties file
2. Dependency management is applied transitively rather than only to
direct dependencies
3. Exclusions are applied as they would be in Maven
4. Gradle-generated poms are automatically configured with the
appropriate dependency management
Closes gh-2133
Previously repackaging of an archive was performed in three steps:
1. Write the manifest
2. Write entries from the source archive into the destination
3. Write any libraries into the destination if they’re not already there
This worked fine for jar files, but not for war files. In the war file
case the libraries are already in the source archive’s WEB-INF/lib
directory so they’re copied into the destination in step 2. This means
that step 3 largely becomes a no-op and, crucially, the UNPACK comment
is not applied to any libraries that require it.
This commit reorders steps 2 and 3 so that the libraries are copied into
the destination first (allowing the UNPACK comment to be written, if
required) and then any entries in the source are written into the
destination if they’re not already there.
Fixes gh-2588
Update ConfigurationMetadataAnnotationProcessor so that `prefix` is
only obtained when the annotation is not null. Also improve exception
message by including the element.
Parse a version using our version format or any version that complies
with Major.Minor.Patch. Also add a VersionRange utility that can
determine if a given version is withing that range.

The Maven plugin allows spring-boot:run to be configured so that
resources are loaded from their output location rather than from
src/main/resources. This commit adds an equivalent configuration
option to the Gradle plugin. To disable source resources from being
added to the classpath in place of those in the output location
the configure the bootRun tasks like this:
bootRun {
addResources = false
}
Closes gh-2431
The main change in this commit is to introduce a new BuildHandler
abstraction. A BuildHandler is responsible for producing the metadata
for a build. Two implementations are provided; one for standard builds
and one for incremental builds. This change means that the annotation
processor is no longer concerned with the two different build types
and can use the same logic in each case.
The code for reading and writing metadata files has also been moved
out into a separate class, MetadataStore, to allow it to be easily
utilised from multiple places.
Closes gh-2313
This commit udpdates the metadata annotation processor so that change
data from an incremental build is merged with the metadata from the
previous build.
Closes gh-2321
This commit adds support for configuring the XA DataSource and
ConnectionFactory pools created by Atomikos and Bitronix via the
environment. The property prefixes vary depending on the transaction
manager that’s in use. They are:
Bitronix:
- spring.jta.bitronix.datasource
- spring.jta.bitronix.connectionfactory
Atomikos:
- spring.jta.atomikos.datasource
- spring.jta.atomikos.connectionfactory
The configuration processor has been updated to ignore
javax.jms.XAConnectionFactory and javax.sql.XADataSource as neither of
these types can be created via property binding.
Closes gh-2027
By default, when building a project's jar its runtime dependencies
are not taken into account as they are not needed to successfully
compile the code that will be packaged in the jar. A side-effect of
this was that, if a project that was being repackaged had a runtime
dependency on another project, then the repackaged jar would not
include the jar of the project on which it has the runtime dependency
as the jar had not been built.
This commit updates Boot's repackage task to have a dependency on the
jar task of any project dependencies in the runtime configuration
thereby ensuring that those dependencies' jars will have been built
before the repackaging occurs.
Fixes gh-2344
Running the invoker plugin with multiple threads against an empty
Maven cache results in strange build failures where Maven claims that
it cannot find a jar or pom file for an artifact that it should be
able to find. It would appear that Maven is unable to cope with
concurrent writes to its cache.
This commit removes the usage of multiple threads that was introduced
in 4e907f1.

If user runs an executable archive then it and its lib directory will be

on the old ones, which probably aought to be beefed up to the same
standard).

Previously, disabling forking was not possible if JVM arguments or an
agent are specified, even if the fork attribute is explicitly set to
`false`.
The fork attribute is now detected as it should and forking is disabled
when the fork attribute is set to false, even if JVM arguments or an
agent is either specified or discovered.

Previously, no configuration properties were discovered on a class using
lombok instead of regular getters/setters.
This commit adds a support for some of the lombok annotations,
specifically that is @Data, @Getter and @Setter. Provides the same
semantic as what lombok is generating.
Closes gh-2114
Previously, non camel case properties were wrongly resolved, i.e.
getFOO() leading to a 'f-o-o'. While unusual, underscores can also be
added to a property name. In that case, the hyphen should not be added
as the binder consider this to be a single "word". Typically setFoo_Bar
on the "something" prefix is mapped using "something.foo_bar".
All these cases are now handled properly, generating the target name that
the binder expects.
Fixes gh-2118
flyway.init and flyway.target are two options that are missing from the
meta-data following the change in f0bc3c0. It turns out that both these
properties have an additional setter taking a String so they shouldn't be
excluded after all
Closes gh-2088
Previously, a property holding an array did not have a proper default
value in the meta-data even though the related field was initialized
properly.
An explicit support for arrays has been added. The "defaultValue" now
holds the default value for singular properties or an array of values for
array-based properties. If the value is initalized with an empty array,
the default value is an empty array as well.
Closes gh-1996
Previously, any valid property was added to the meta-data of the current
group. This can be annoying for types that are not meant to be bound from
a simple string value. ClassLoader is one example.
A list of well-known types has been added: if the property type matches
an element of this list, it is ignored.
Fixes gh-2012
Previously, any property defined in a @Deprecated class were not marked
as deprecated as only the getter or field was inspected for the

An additional check on the class has been added to handle this case.

Update the ConfigurationMetadataAnnotationProcessor nested class
algorithm to prevent inner classes being added as both groups and
properties.

Previously, an Enum that is defined as an inner class of a
@ConfigurationProperties pojo was wrongly detected as an nested group.
This case is now handled explicitly and covered by a test.

Add a companion module that IDE developers can use to read configuration
metadata from multiple sources into a single repository.

Add a 'module' layout for the repackager which includes all 'compile'

Previously, WarLauncher included its root on the classpath. It also used
a filtered version of its root archive to hide both the WEB-INF and
META-INF directories. This meant that files in WEB-INF and META-INF
could be found by the classloader (as they were on the classpath) but
could not be read as the filtered archive was hiding them.
This commit updates WarLauncher to remove the root of the war file from
the classpath. It also removes the filtering of the archive, thereby
allowing files in META-INF and WEB-INF to be accessed via the
ServletContext.

Update TypeElementMembers to correctly detect builder style setters.
The previous logic could fail because of the crazy way that TypeMirror
implements its equals() method.

Previously, a setter method that was returning the current instance was
not identified as a "setter" by the configuration processor. As a result,
builder-style APIs were not covered by the configuration metadata.
If a setter returns either void or the current class, it is now
recognized as a valid setter.

Add a @NestedConfigurationProperty annotation which can be used to
customize how configuration mete-data is generated.
Prior to this commit only inner-classes where considered nested
(see Tomcat in ServerProperties). Using this new annotation, the Ssl
property in ServerProperties can be detected as well.
See gh-1001
Update `ConfigurationMetadataAnnotationProcessor` to include the
'defaultValue' of a property when possible. For example the
'defaultValue' or 'server.port' is '8080'.
Default values are detected by inspecting the field assignments of
@ConfigurationProperties items. In order to detect field values some
internals of the Java compiler are used. To save a dependency on
'tools.jar' internal javac classes are accessed using reflection.
See gh-1001
Adds an annotation processor to generates a JSON meta-data file at
compile time from @ConfigurationProperties items. Each meta-data file
can include an array or 'properties' and 'groups'.
A 'property' is a single item that may appear in a Spring Boot
'application.properties' file with a given value. For example,
'server.port' and 'server.context-path' are properties. Each property
may optionally include 'type' and 'description' attributes to provide
the data type (e.g. `java.lang.Integer`, `java.lang.String`) and
some short documentation (taken from the field javadoc) about what the
property is for. For consistency, the type of a primitive is translated
to its wrapper counterpart, i.e. `boolean` becomes `java.lang.Boolean`.
A 'group' provides a higher level grouping of properties. For example
the 'server.port' and 'server.context-path' properties are in the
'server' group.
Both 'property' and 'group' items may additional have 'sourceType' and
'sourceMethod' attributes to indicate the source that contributed them.
Users may use `META-INF/additional-spring-configuration-metadata.json`
to manually provide additionally meta-data that is not covered by
@ConfigurationProperties objects. The contents of this file will be
read and merged with harvested items. The complete meta-data file is
finally written to `META-INF/spring-configuration-metadata.json`.
See gh-1001
Previously, the Gradle plugin’s ProjectLibraries produced a new library
for every file dependency, even if the dependencies where on the same
file. This would lead to a repackaging failure due to multiple
libraries having the same name.
This commit updates ProjectLibraries to treat file dependencies on the
same file as a single library, thereby resolving the name clash.
Fixes gh-1646
The fix for gh-1475 introduced the use of an artifact's group to
discriminate between two libraries with the same name (artifact id)
and version. However, in the case of Gradle, a group name was not
provided for libraries that have been resolved from a repository.
This commit updates ResolvedArtifactLibrary to use the group obtained
from the underlying ResolvedArtifact as its discriminator.
Fixes gh-1543
The applicationDefaultJvmArgs property was added in Gradle 1.7. This
commit updates RunPluginFeatures to access the property defensively
so that the plugin can be used with Gradle 1.6.
Fixes gh-1511
Prior to this commit, the repackage goal silently ignored the case of
two libraries having the same name and version but a different group.
As a result, the second library was overwriting the first one in the
repackaged jar.
This commit adds support for custom Library names and updates the
Maven and Gradle plugins so that the name includes the group ID
when there would otherwise be a duplicate.
Fixes gh-1475
This commit clarifies the role of the 'addResources' flag and makes
it explicit that any duplicate found in the target directory are
actually removed
Fixes gh-1479
This commit adds a 'skip' parameter to the 'repackage' goal that is
false by default. When this parameter is enabled, the repackage goal
does not run at all.
This can be used when repackaging should occur conditionally or
when a particular module in a hierarchy should not use this feature.
Fixes gh-1424
Previously, ProjectLibraries only considered a configuration's
direct file dependencies. This meant that a transitive file
dependency that should have been pulled in via a project dependency
was not included in the repackaged jar's lib directory.
ProjectLibraries has been updated to walk down the tree of project
dependencies and create libraries for any file dependencies that
are found.
Fixes gh-1368
* Windows: allow absolute file paths without file:/// prefix
* All: only add nested archives (not directories), so loader.path=lib/*

The ExplodedArchive would erroneously always attempt to filter
its contents (and thereby shield them from a classloader that wrapped
it) even if they haven't been explicitly provided.

Previously, Repackager would repackage a jar file as many times as
it was asked to do so. This lead to problems if a user made a mistake
when using Maven that led to the package phase being driven twice,
for example by running "mvn clean install package".
This commit updates Repackager so that a repackage call becomes a
no-op if the source jar's manifest already contains the
Spring-Boot-Version attribute which is added by repackaging.

Before this change a property whose key was in a non-enumerable property source would
not resolve placeholders, leading to ${style} values in @ConfigurationProperties beans
even if the placeholders ere resolvable.
This commit refines the changes made under 4be688aa. 4be688aa made the
default jar task a special case which broke repackaging of the archive
produced by the default war task.
This commit refines RepackageTask’s logic so that, when it’s enabled,
it will repackage a jar task’s archive if:
- The jar task is equal to RepackageTask.withJarTask
- The name of the jar task is equal to RepackageTask.withJarTask
- RepackageTask.withJarTask is null, the jar task is not referenced
by another RepackageTask’s withJarTask, and the jar task has an
empty classifier
The last of these three is the default case and ensures the, when the
Spring Boot plugin is applied, default jar and war artifacts are
repackaged. The classifier check is required to prevent default source
and javadoc artifacts from being repackaged.
Fixes#1204
The logic that determined whether or not the repackaging action should
be applied to a particular jar task was broken and caused problems
when a custom RepackageTask was used in a project's build.
This commit updates the logic so that repackaging will be applied:
- To the default jar task if RepackageTask.withJarTask is null
- To a jar task if it is equal to RepackageTask.withJarTask
- To a jar task if its name is equal to RepackageTask.withJarTask
Repackaging is not applied if:
- RepackageTask.enabled is false
Numerous integration tests have been added to verify the repackaging
behaviour.
Fixes#1204
The new ResolvedArtifact-based minus implementation was checking the
wrong Set when deciding whether or not a ResolvedArtifact should
be included in the result. This was leading to provided dependencies,
that should have only been packaging in WEB-INF/lib-provided also
being packaged in WEB-INF/lib.
The WarPackaging tests have been updated. In addition to checking that
WEB-INF/lib-provided does not contain anything that’s unexpected, they
also verify the contents of WEB-INF/lib
Fixes#1187
Fix 'fat jar' support for windows to correctly deal with URL and path
slash issues. The root cause of the original problem was caused by JAR
URLs not including a root slash (ie `file:C:/Users` vs `file:/C:/Users`)
Fixes gh-1145
Update ExecutableArchiveLauncher so that `-cp` URLs are not added
when they are already contained as nested JARs. This prevents a
SecurityException "signer information does not match error" when using
signed jars. The root cause of the issue was that the primary JAR file
was on the default classpath with the URL "file:....jar" and in the
main URL set as "jar:file:....jar". It is now filtered so that only
the "jar:" variant is added.
Fixes gh-1134
Update the executable JAR code to automatically unpack any entries
which include an entry comment starting `UNPACK:` to the temp folder.
The existing Maven and Gradle plugins have been updated with new
configuration options and the `spring-boot-tools` project has been
updated to write the appropriate entry comment based on a flag passed
in via the `Library` class.
This support has been added to allow libraries such a JRuby (which
assumes that `jruby-complete.jar` is always accessible as file) to work
with Spring Boot executable jars.
Fixes gh-1070
Add a Library class update the LibraryCallback interface and
implementations to use it. This change is in preparation for
an addition `unpack` flag that will be required to allow the
automatic unpacking of certain nested jars.

Update JarURLConnection to allow the resolution of items within a nested
jar, even if the jarFile passed to the connection is several levels up.
This prevent a connection from incorrectly resolving an entry against
the wrong jar file.
See gh-1070
Tweak 'fat jar' handling to generally improve performance:
- Allow JarURLConnection to throw a static FileNotFoundException when
loading classes. This exception is thrown many times when attempting
to load a class and is silently swallowed so there is no point in
providing the entry name.
- Expose JarFile.getJarEntryData(AsciiBytes) and store AsciiBytes in
the JarURLConnection. Previously AsciiBytes were created, discarded
then created again.
- Use EMPTY_JAR_URL for the JarURLConnection super constructor. The URL
is never actually used so we can improve performance by using a
constant.
- Extract JarEntryName for possible caching. The jar entry name
extracted from the URL is now contained in an inner JarEntryName
class. This could be cached if necessary (although currently it is
not because no perceivable performance benefit was observed)
Fixes gh-1119
Update JarFile to reuse the previously parsed entries when creating
filtered jars. This saves needing to re-scan the underlying file to
recreate a subset of entries.
See gh-1119
Drop JarEntryFilter arguments from the JarFile constructor and the
getNestedJarFile methods. Filtered JarFiles can still be obtained by
using the getFilteredJarFile() method.
This helps simplify the code a little and will make it easier to add
caching.
See gh-1119
The default behaviour doesn't change with this commit, but now
the user has the option to specify a 'classifier' property
either in springBoot { classifier = 'exec' } (i.e. globally
for all repackage tasks) or in each repackage task, e.g.
bootRepackage { classifier = 'exec' }. In that case the original
archive is not overwritten but copied into <file>-<classifier>.jar
(or .war etc.) and then enhanced.
Fixes gh-1113, fixes gh-141 also I believe.
The class Compile was deprecated and will be removed in Gradle 2.0 (it is

Instead we should use JavaCompile. Fixes gh-1066.

Simplify the exclusion logic used in Gradle by implementing implicit
exclusions rather than trying to detect transitive excludes.
This commit reverts much of the code originally included to fix gh-1047

the underlying issue.

Update `spring-boot-loader` ZIP processing code to support prefixed

Previously, the versionManagement configuration was resolved as part of
the Boot Gradle plugin being applied. This meant that no dependencies
could be added to it and attempting to do so would result in a failure:
“You can't change a configuration which is not in unresolved state”.
This commit updates ApplyExcludeRules to wrap its processing in a
before resolve action. This defers the resolution of the
versionManagement configuration until one of the project’s other
configurations is being resolved. Fixes#1077
In addition to the above, the transitive exclusions that the Gradle
plugin provides were being lost if custom version management provided
a version for the same dependency. This commit updates
AbstractDependencies to preserve the exclusions from an existing
dependency declaration while using the version from the newer
dependency. This ensures that the exclusions remain while allowing
versions to be overridden. Fixes#1079
