This commit adds configuration to the Spring Boot Gradle plugin that
allows the names and contents of layers to be customized in the build
configuration.
Fixes gh-20296
Maven's war plugin does not support reproducible builds, resulting in
the entries in the war file not being written in a consistent order
from build to build.
Closes gh-20176
This commit adds an additional 'layers/configuration' property that can
be used to refer to a separate layers configuration file. This separate
file defines:
* The layers and their order of precedence,
* How libraries are handled using filters that match against the
coordinates of each library, and
* How classes are handled using filters that match against the location
of the entry
An XSD to validate the XML configuration file is available.
Closes gh-20295

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
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.
Closes gh-19767

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.

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
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
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.
