Previously, when writing a repackaged jar, an attempt to write all of
an entry's parent directories would always be made, irrespective of
whether or not the entry itself had already been written. This was
inefficient as, due to the way that the jar is written, once an entry
itself has been written, we know that all of its parent directories
will also have been written.
This commit updates the jar writer so that no attempt is made to
write parent directory entries if the entry itself has already been
written.
Fixes gh-29175
An upgrade to Apache Commons Compress allows the build plugins to write
the launch script to the fat jar as a proper preamble, making the file
compatible with more jar and zip tooling.
Fixes gh-22336
Update `RepackageMojo` and supporting classes so that `exclusions`
on the repackage goal apply to both the contributed libraries and any
existing jar entries already contained in the original war.
Prior to this commit, exclusions would apply to contributed jars (for
example, those in `WEB-INF/lib-provided`) but not jars that were
packaged directly into `WEB-INF/lib` by the war plugin

Update `Repackager` to ensure that `getLayout` is called before we
backup the source file. This restores earlier behavior that some
custom `ModuleFactory` implementations were relying on.
Closes gh-22995
Prior to this commit, when the Maven plugin copied
spring-boot-loader.jar to a repackaged archive the timestamps of class
files were preserved but the timestamps of directories were not
preserved. This resulted in the directories having a current timestamp.
This commit copies the directory timestamps from spring-boot-loader.jar
to the repackaged archive and adds tests to verify the proper
behavior.

Update the Maven plugin so that layered jars now use the regular "flat"
format. The layers.idx file now describes which layer each file should
be placed.

Create a dedicated layer that is used to hold the launcher support
classes. The layer sits between `dependencies` and
`snapshot-dependencies` so that the layer is sensible for both
SNAPSHOT and RELEASE versions of Spring Boot
Closes gh-20529
Simplify layer customization logic for both Maven and Gradle and
refactor some internals of the Gradle plugin.
Both Maven and Gradle now use a simpler customization format that
consists of `application`, `dependencies` and `layer order` sections.
The `application`, `dependencies` configurations support one or more
`into` blocks that are used to select content for a specific layer.
Closes gh-20526
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
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.

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.
Closes gh-9128

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
