Previously, the "classifier" attribute was only used to determine the
target classifier of the repackaged archive, always using the main
artifact as the source.
This commit changes the semantic of the attribute so that an existing
archive matching the "classifier" attribute can be used as source,
replacing the archive the same way the goal replaces the main archive
if no classifier is found.
If no artifact with the specified classifier exists, the repackaged
archive is still processed based on the main archive and attached to
the lifecycle using the value of the classifier attribute.

Upgrading the JDK 9-based build to use JDK 9.0.4 has revealed that
Gradle 4.0.x doesn't work with it as it fails to parse the 9.0.4
version number.
This commit disables building the Gradle plugin on Java 9 (as we
had already done for Java 10) until we decide what to do
(see gh-12333).
While being able to exclude all artifacts of a given group is a handy
feature, excluding all artifacts with a given artifactId does not make
much sense as it should refer to a single artifact anyway. Also the
general "exclude" mechanism is meant to do the exact same thing.

Previously, the underlying RandomAccessDataFile was not closed when
the JarFile that was using it was closed. This causes a problem on
Windows as the open file handle prevents the file from being deleted.
This commit updates JarFile to close the underlying
RandomAccessDataFile when it is closed and has a JarFileType of
DIRECT.
Previously, when accessing the manifest of a jar file that maps to a
nested directory (BOOT-INF/classes) a new JarFile was created from the
root jar file, the manifest was retrieved, and the new JarFile was
closed. This could lead to the underlying RandomAccessDataFile being
closed while it was still in use.
This commit improves JarFile to retrieve the manifest from the
existing outer JarFile, thereby avoiding the need to create and close
a new JarFile.
Unfortunately, PropertiesLauncher creates a number of scenarios where
a JarFile with a type of direct is closed while it’s still being used.
To accommodate this behaviour, RandomAccessDataFile has been updated
so that it can re-open the underlying RandomAccessFile if it is used
after it has been closed.
Closes gh-12296
This commit updates the annotation processor and the binder to ignore
any static or abstract method that has the characteristics of a JavaBean
accessor. As a result, no property is generated for those (invalid)
accessor and no binding occurs on them either.

With JDK 8 being the baseline and JDK 7 not being supported anymore we
can get rid of the workaround for a JDK 7 bug in
ProcessBuilder.inheritIO on Windows machines.

Previously, the JDK 10 build would fail as we build the plugin using
Gradle 4.0.x (the lowest version of Gradle that we support) and
Gradle 4.0.x doesn't work with Java 10.
Upgrading to Gradle 4.1, which appears to work with Java 10, was
considered but rejected for now as it introduces the risk that we
inadvertently use an API that's new in 4.1 and break our 4.0 support.
This commit goes for the extreme option and disables building the
Gradle Plugin when building with JDK.

Previously, if the project's group, name, or version changed the
BuildInfo task would still be considered up-to-date as the values of
the project's properties were not reflected in the fields of the
BuildInfo instance.
This commit updates BuildInfo to copy the value of the project's
property to the corresponding BuildInfo field when the property is
read using its getter method on BuildInfo.
Closes gh-12266
Previously, working with a JarFile created a large amount of garbage
that was allocated on the thread local allocation buffer (TLAB).
The TLAB allocations made a significant contribution to GC pressure
and slowed down startup. This commit reduces the amount of garbage
by making a number of changes.
Reading from a RandomAccessDataFile has been reworked to avoid
creating new RandomAccessFile instances. A single RandomAccessFile
is now created for an entire jar file and it is used to read data from
anywhere in that jar file, including entries in nested jar files. To
ensure that reads remain thread-safe, a lock is taken on the
RandomAccessFile that is shared by all RandomAccessDataFile instances
that are provided access to (portions of) the same jar file.
Reading all of the bytes from a RandomAccessData has been reworked to
avoid the use of an InputStream that was created, used to read the
data, and then thrown away. In place of the InputStream-based
mechanism a method has been introduced that returns all of the
RandomAccessData as a byte[]. Building on this change, a method has
also been introduced to read a portion of a RandomAccessData as a
byte[]. This avoids the need to create a new RandomAccessData
subsection where the subsection was only used to read its entire
contents and then thrown away.
Decoding of an MS-DOS datetime has been reworked to use LocalDataTime
rather than GregorianCalendar. The former produces less garbage than
the latter.

This commit changes invocations to immediately return the expression
instead of assigning it to a temporary variable. The method name should
be sufficient for callers to know exactly what will be returned.
Closes gh-12211
Previously, the order of the entries in a TestJarFile was determined
by the underlying file system rather than by the order in which
they were added. This could lead to unpredicatable ordering and
failures in tests that verify archive entry ordering.
This commit updates TestJarFile to add entries to the archive in
insertion order.
See gh-11695
See gh-11696
Previously, the Repackager would write entries in the following
order:
- Libraries that require unpacking
- Existing entries
- Application classes
- WEB-INF/lib jars in a war
- Libraries that do not require unpacking
- Loader classes
Libraries that require unpacking were written before existing entries
so that, when repackaging a war, an entry in WEB-INF/lib would not
get in first and prevent a library with same location from being
unpacked. However, this had the unwanted side-effect of changing
the classpath order when an entry requires unpacking.
This commit reworks the handling of existing entries and libraries
that require unpacking so that existing entries can be written first
while also marking any that match a library that requires unpacking
as requiring unpacking.
Additionally, loader classes are now written first. They are the
first classes in the jar that will be used so it seems to make sense
for them to appear first. This aligns Maven-based repackaging
with the Gradle plugin's behaviour and with the structure documented
in the reference documentation's "The Executable Jar Format" appendix.
The net result of the changes described above is that entries are
now written in the following order:
- Loader classes
- Existing entries
- Application classes
- WEB-INF/lib jars in a war marked for unpacking if needed
- Libraries
Closes gh-11695
Closes gh-11696
Previously, the ordering of the entries in an archive produced by
BootJar was different to the ordering of the entries in an archive
produced by BootWar. The latter placed application classes before
any nested jars, whereas the former was the other way around.
This commit updates BootJar to use the same ordering as BootWar and
adds tests to verify that the ordering is the following:
1. Loader classes
2. Application classes (BOOT-INF/classes or WEB-INF/classes)
3. Nested jars (BOOT-INF/lib or WEB-INF/lib)
4. Provided nested jars in a war (WEB-INF/lib-provided)
The tests also verify that the position of a library is not affected
by it requiring unpacking.

Stop running apply-plugin tests as part of the build since during a

Update a couple of the `spring-boot-gradle-plugin` sample gradle flies
so that they include the running classpath. The additional lines are
contained within a tag which is ultimately filtered from the final
documentation.

This commit makes sure that a "cache.time-to-live" property is not
generated for endpoints that do not have a main read operation (i.e. a
read operation with no parameter or only nullable parameters).
This matches the endpoint feature that provides caching for only such
operation.
Closes gh-11703
On CI, Cassandra running inside the Docker container sometimes fails
to start or the start times out. This has nothing to do with Boot so
we attempt to protect our tests from the flakiness of the container
by allowing 3 startup attempts.
As `validation-api` 2 is available by default, this commit adds the
integration test as a regular test case. The integration test is kept to
exercise what happens in a standard project.

This commit removes the use of the incubating PropertyState and
Provider API that was introduced in Gradle 4.0 and deprecated in
Gradle 4.3. A not-deprecated-but-still-incubating replacement was
introduced in Gradle 4.3. The short life of PropertyState and Provider
has made me wary of using an incubating Gradle API in our public API
as it may not be stable for long. Therefore, this commit does not move
to the replacement as it is incubating. Instead, it falls back to
using Gradle's convention mapping. This is internal API, but its use
is not part of our public API and I perceive the risk of using it to
be lower than using the deprecated and/or incubating API alternatives.
Closes gh-11640
Update the `LaunchedURLClassLoader` used for fat jar support so that
each iteration on a `findResources` result also allows for fast
exceptions.
Fixes gh-11406
Refactor fat jar loader classes so that less `char[]` instances are
created. This is primarily achieved by adding a new `StringSequence`
class that can chop up Strings without needing to copy the underlying
array. Since Java 8, calls to `String.subString(...)` always copy the
underlying char array. For many of the operations that we need, this
is unnecessary.
Fixes gh-11405
Update the configuration properties annotation processor to deal
with `Duration` based default values. For example a field that
defaults to `Duration.ofSeconds(10)` will have a meta-data default
value of `10s`.
See gh-11080
Update endpoint code to provide cleaner separation of concerns.
Specifically, the top level endpoint package is no longer aware of
the fact that JMX and HTTP are ultimately used to expose endpoints.
Caching concerns have also been abstracted behind a general purpose
`OperationMethodInvokerAdvisor` interface.
Configuration properties have been refined to further enforce
separation. The `management.endpoint.<name>` prefix provides
configuration for a single endpoint (including enable and cache
time-to-live). These properties are now technology agnostic (they
don't include `web` or `jmx` sub properties).
The `management.endpoints.<technology>` prefix provide exposure specific
configuration. For example, `management.endpoints.web.path-mapping`
allow endpoint URLs to be changed.
Endpoint enabled/disabled logic has been simplified so that endpoints
can't be disabled per exposure technology. Instead a filter based
approach is used to allow refinement of what endpoints are exposed over
a given technology.
Fixes gh-10176
The Gradle plugin integration tests find their Gradle build scripts
using a naming convention of ${ClassName}-${methodName}.gradle. This
convention led to two gradle scripts with filenames that were long
enough to causes problems on Windows.
This commit renames two test methods to reduce the length of their
names and, therefore, the names of their corresponding Gradle script
files.
