This documentation moves the specific `build-image` execution
configuration example of the Maven plugin documentation to the general
plugin configuration. This makes sure that it works in most cases and
an execution-specific configuration is not required here anyway.
Closes gh-19946
With the introduction of Gradle we lost the list of version properties
that were previously in the spring-boot-dependencies POM and were also
linked inside the documentation. This commit introduces an appendix
section in the docs and links the appropriate places to the new section
to restore discoverability.

Previously \r\n was used on Windows and \n was used on other
platforms. This resulted in different JSON content being written to
the archive. As the config's entry name is the SHA-256 hash of its
content, it also resulted in the entry name being different.
This commit updates the JSON that's written into the archive to use
\n line endings, irrespective of the OS on which the image is being
built.
See gh-19828
We build with Java 8, 11, and 13 without specifying target
compatibility for the bytecode of the app that's placed in the image.
The built image uses Java 11 and when the app is built with Java 13
it fails to start as the Java 11 VM can't read that Java 13 bytecode.
This commit configures the app that's placed in the image to be built
with target compatibility of 1.8. This allows it to be compiled with
all version of Java with which we build and to also be compatible
with the JVM that's in the image.

This commit changes uses of ClassLoader.loadClass to Class.forName for
consistency with what was initiated in #19342 and better compatibility
with GraalVM.
Closes gh-19824
Update `LaunchedURLClassLoader` to ensure that the `JarModeLauncher`
is created in the correct classloader.
Prior to this commit the launcher was created by the application
classloader and did not have access to any of the required
`org.springframework` classes.
See gh-19848
Update all dependencies declarations to use the form `scope(reference)`
rather than `scope reference`.
Prior to this commit we declared dependencies without parentheses unless
we were forced to add them due to an `exclude`.
Replace Gradle single quote strings with the double quote form
whenever possible. The change helps to being consistency to the
dependencies section where mostly single quotes were used, but
occasionally double quotes were required due to `${}` references.
Fix a bug in `ExplodedURLClassLoader` and merge the code into the
existing `LaunchedURLClassLoader` class. Also polish a few method
names relating to layer support.

Rename the `spring-boot-cloudnativebuildpack` module to
`spring-boot-buildpack-platform` and update the the package
name to `org.springframework.boot.buildpack.platform`.
Closes gh-19851
Add a new `spring-boot-layertools` module which provides jarmode support
for working with layers. The module works with both classic fat jars,
as well as layered jars.
Closes gh-19849
Update the `Launcher` class to allow a packaged jar to be launched in
a different mode. The launcher now checks for a `jarmode` property and
attempts to find a `JarMode` implementation using the standard
`spring.factories` mechanism.
Closes gh-19848
Previously, the generated resources were added as an output to the
main source set. This worked on the command line, but resulted in
the META-INF folder that contains the loader jar not being on the
classpath of downstream projects in Eclipse.
This commit changes loader-tools to add the generated resources
as a srcDir to the main source set. This results in it appearing on
the classpath of other projects in Eclipse that depend on loader-tools
such as the Gradle plugin, thereby allowing its tests to be run in
the IDE as well as on the command line.
Fixes gh-19841
Pull functionality from `Repackager` into a new `Packager` base class
and develop a variant for Docker image creation. The new `ImagePackager`
class provides a general purpose way to construct jar entries without
being tied to an actual file. This will allow us to link it to a
buildpack and provide application content directly.
Closes gh-19834
Add a Java implementation of the buildpacks.io specification allowing
projects to be packaged into OCI containers. The `builder` class
provides a Java equivalent of `pack build` command and is based on
the `pack` CLI Go code published at https://github.com/buildpacks/pack.
Closes gh-19828
Support an alternative fat jar format that is more amenable to Docker
image layers.
The new format arranges files in the following structure:
BOOT-INF/
layers/
<layer-name #1>
/classes
/lib
<layer-name #2>
/classes
/lib
The `BOOT-INF/layers.idx` file provides the names of the layers and the
order in which they should be added (starting with the least changed).
The `JarLauncher` class can load layered jars in both fat and exploded
forms.

Update the `Repackager` class so that an additional `classpath.idx` file
is written into the jar that provides the original order of the
classpath. The `JarLauncher` class now uses this file when running as
an exploded archive to ensure that the classpath order is the same as
when running from the far jar.
Closes gh-9128

The JarFile was not being closed which linked a file handle and caused
a test failure on Windows.
The local variable has been renamed as, when declared in a
try-with-resources, Checkstyle was confused by the shadowing of the
jarFile field and required references to jarFile within the try-block
the be prefixed with this.

This paves the way for publishing Gradle module metadata once the
problem caused by snapshot versions and our two-step publication
process has been addressed.
See gh-19609
This reverts commit b34a311d02 as,
having disabled the publishing of Gradle's module metadata (4f75ab5),
the changes are no longer needed.

Previously, enforcedPlatform dependencies were using to pull in the
constraints defined in spring-boot-dependencies and
spring-boot-parent and applied them strictly so that the constrained
version had to be used. This worked as intended in Spring Boot's own
build but incorrectly enforced those same strict version requirements
on external consumers of Spring Boot's modules.
This commit reworks how Spring Boot defines its internal dependency
management so that platform dependencies are exposed to external
consumers while enforced platform dependencies are using internally.
See gh-19609
Enforcing the spring-boot-dependencies platform makes for too strong
an opinion about the version of Kotlin that should be on the build
script's classpath. It clashes with the version of Kotlin that's
embedded in Gradle and used with Gradle's Kotlin DSL.
This commit switches to a normal platform (rather than an enforced
platform) which allows it to express an opinion about the version of
Kotlin without making it a strict requirement.
Closes gh-19609
Update `AutoConfigureAnnotationProcessor` to ensure that the generated
properties file is fully repeatable. Properties are now sorted and
written out directly to ensure that the timestamp comment is not
present.
Closes gh-19370
- Previously, we would create a JarFileArchive for all nested jars.
This was an additional overhead. We only need to create a JarFileArchive
for jars that can have nested jars in them. For all other jars we only need
the URL to build the classpath.
- While iterating over nested entries in the exploded jar, we only need to
look at BOOT-INF and we can skip any entry that does not match that.

Previously, reflective access to the archiveBaseName property
incorrectly treated the property as a String. It should have been
treated as a Property<String>. This caused an exception to be thrown
and the deprecated baseName property to be used as a fallback.
This commit corrects the reflective access to the archiveBaseName
property. It also updates the tests to fail if a build outputs a
deprecation warning. Tests that use Gradle's Maven plugin have been
updated to expect deprecation warnings when run with Gradle 6.0 where
the plugin is deprecated. Tests that configure an archive's base name
have been updated to use archiveBaseName when running with Gradle 6.0
and later.
Closes gh-18663
Previously, our Gradle plugin was not tested against Gradle 6.0,
a number of deprecation warnings were output when using the plugin
with Gradle 6, and some functionality related to the application
plugin did not work as expected.
This commit tests the plugin against Gradle 6. It also avoids calling
deprecated APIs. The plugin is compatibile against Gradle 4.10 where
the deprecated APIs' replacements are not available so reflection is
used to call the replcaements. Lastly, the way in which the base name
of the boot distribution that is created when the application plugin
is applied has been modified to ensure that it is effective when using
Gradle 6.
Closes gh-18663
Previously, when RunProcess handled a SIGINT it would immediately
attempt to destroy the process that it had run. This created a race
condition between the SIGINT being handled by the child process
and RunProcess destroying the child. The exact behavior of destroy
is implementation dependent and it may result in forcible termination
of the process where shutdown hooks are not called. This is what
happens on Windows. The exit code in such a case is 1 which prevents
anything from waiting for the process to complete from detecting
that it ended as a result of a SIGINT, leaving it with no choice but
to report an error. This is what happens with mvn spring-boot:run
with a forked process on Windows and results in the build failing.
This commit updates RunProcess to allow the child process to handle
the SIGINT itself, waiting for up to five seconds for that to happen
before the process is then destroyed. Given this time, the child
process exits with 130 which RunMojo already handles correctly as
indicating that the process died due to SIGINT and the build completes
with success as a result.
Fixes gh-18936
Previously, when the configuration properties annotation processor
encountered a property that was the same as an outer type that had
already been processed, it would fail with a stack overflow error.
This commit introduces the use of a stack to track the types that
have been processed. Types that have been seen before are skipped,
thereby preventing a failure from occurring. We do not fail upon
encountering a recursive type to allow metadata generation to
complete. At runtime, the recursive property will not cause a problem
if it is not bound.
Fixes gh-18365
Update `AutoConfigureAnnotationProcessor` to no longer store
`@Configuration.value` in the meta-data JSON since we never actually
read it.
Closes gh-16608
Update the configuration processor to use the newly introduced
`@ConstructorBinding` annotation to determine when meta data
should be generated from constructor parameters.
Prior to this commit, the processor had no good way to tell when
constructor parameters should be used instead of getters/setters.
Closes gh-17035
Previously, Maven's default behaviour was relied up which resulted
in the artifact ID being appended to each URL as it was inherited.
This behaviour can only be disabled in Maven 3.6 and later, a version
that we cannot use due to an incompatibility with the Flatten Plugin.
This commit works around Maven's default behaviour by defining
properties for the SCM URL, connection, and developer connection and
then explicitly defining the settings in each pom using these
properties. The explicit definition of the properties in each pom
prevents them being inherited from the parent, thereby disabling the
unwanted appending of the artifact ID to the URL.
Fixes gh-18328
This commit makes sure that a ConfigurationProperties type contributed
by a `@Bean` factory method uses properties binding regardless of the
presence of a matching constructor.
`@Bean` method makes sure the user is in control and will be responsible
of creating the instance. As a result, binding of properties will not
happen there and therefore can only happen with regular JavaBean
accessors.
Closes gh-18184
Previously, calling getComment() on a nested jar file would result
in the outer jar file's comment being returned.
This commit updates the loader's JarFile to read the file's comment
from the central directory end record and return it from getComment().
Fixes gh-18128
Previously, the configuration processor would ignore any
@ConfigurationProperties-annotated methods that were not public. This
prevented metadata generation for package-private @Bean methods such
as those in DataSourceConfiguration's inner-classes for DBCP2, Hikari,
and Tomcat JDBC.
This commit updates the annotation processor so that it will process
any non-private method annotated with @ConfigurationProperties.
Fixes gh-18124
This commit prevents a potential NPE if the startTime of the
MavenSession is not available and fallbacks to the current time. This
can happen when invoking the plugin with Maven embedded in an IDE.
Closes gh-17810
Update `BuildInfoMojo` so that the time property now defaults to
`${session.request.startTime}` rather than the time the Mojo was
created. Also update javadoc to make it clear that any supplied
value will be passed to `Instant.parse`.
See gh-17390
Meta-annotate `ClassPathExclusions` and `ClassPathOverrides` with
so that the `ModifiedClassPathExtension` no longer needs to be
used directly.
See gh-17491
Replace any direct `junit-platform-launcher` dependencies and instead
rely on the test runner providing it. Launcher related class are not
handled via reflection.
This update allows us to workaround SUREFIRE-1679.
Closes gh-17517
Add a JUnit 5 extension that allows tests to be run with a
modified classpath. Since JUnit 5 does not currently offer a way
to run tests with a different classpath, we instead fake the
original invocation and launch an entirely new run for each
method.
See gh-17491
Apply checkstyle rule to ensure that private and package private
classes do not have unnecessary public methods. Test classes have
also been unified as much as possible to use default scoped
inner-classes.
Closes gh-7316
Previously, a regular expression of /./ was used to replace /./ with
/. The '.'' in the expression matches any single character so the
replacement was more broadly applicable than it should have been. For
example, /a/ would be replaced with /.
This commit uses Pattern.LITERAL to compile the regular expression
from the CURRENT_DIR (/./) contant. This allows the constant to be
used to check for occurances of /./ in the string before attempting
replacement, while also ensuring that the '.' is treated literally.
Closes gh-17341
Update Gradle archive tasks to ensure that `META-INF/` and
`META-INF/MANIFEST.MF` remain as the first entries of the archive.
Prior to this commit, rewritten archives would violate the implicit
specification of `JarInputStream` that these entries should be first.
Fixes gh-16698
Since the move to JUnit 5, a number of tests were failing on Windows.
The majority were failing due to open file handles preventing the
clean up of the tests' temporary directory. This commit addresses
these failures by updating the tests to close JarFiles, InputStreams,
OutputStreams etc.
A change has also been made to CachingOperationInvokerTests to make
a flakey test more robust. Due to System.currentTimeMillis() being
less precise on Windows than it is on *nix platforms, the test could
fail as it would not sleep for long enough for the TTL period to have
expired.
This commit auto-configures the Elasticsearch REST client support
as a template for Spring Data Elasticsearch. As of this commit,
using the transport client is still possible but developers
should migrate.
This commit also removes the deprecated annotation on the
Elasticsearch auto-configuration for the transport client, since
this deprecation notice is already present on the configuration
property.
