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
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

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.
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
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.

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 b34a311d02fe60ac267493ccc7f2c6b816f3a15c 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.
