Adds a new jarmode called 'tools'. This provides two commands,
'extract' and 'list-layers'. list-layers is the same as list from
the layertools.
extract is able to extract the JAR in four different modes:
- CDS compatible extraction with libraries in a lib folder and a runner
.jar
- CDS compatible as above, but with layers
- Launcher based
- Launcher based with layers. This is essentially the same as extract
from the layertools
The commands in layertools have been deprecated in favor of the commands
in 'tools'.
This also changes the behavior of layers.enabled from the Gradle and
Maven plugin: before this commit, layers.enabled prevents the inclusion
of the layer index file as well as the layertools JAR.
After this commit, layers.enabled only prevents the inclusion of the
layer index file.
layer.includeLayerTools have been deprecated in favor of includeTools,
and the layertools JAR has been renamed to tools.

Update Gradle and Maven plugins to write an empty `META-INF/BOOT.SF`
file whenever there is a nested signed jar.
This update allows Oracle Java 17 to correctly verify the nested JARs.
The file is required because `JarVerifier` has code roughly equivalent
to:
if (!jarManifestNameChecked && SharedSecrets
.getJavaUtilZipFileAccess().getManifestName(jf, true) == null) {
throw new JarException("The JCE Provider " + jarURL.toString() +
" is not signed.");
}
The `SharedSecrets.getJavaUtilZipFileAccess().getManifestName(jf, true)`
call ends up in `ZipFile.getManifestName(onlyIfSignatureRelatedFiles)`
which is a private method that we cannot override in our `NestedJarFile`
subclass. By writing an empty `.SF` file we ensure that the `Manifest`
is always returned because there are always "signature related files".

Create alternative launcher classes under the package
`org.springframework.boot.loader.launch` and use them in favor
of the previous location.
This update is designed to improve compatibility with future
changes in the loader.

Accessing bind mount directories as is done in the tests for building
images with bind mount caches requires Docker configuration when
using Docker Desktop. It works without configuration on Linux with
Docker Engine.
See gh-28387
When building an image using the Maven `spring-boot:build-image` goal or
the Gradle `bootBuildImage` task, the build and launch caches can be
configured to use a bind mount as an alternative to using a named
volume.
Closes gh-28387
This clarifies what used to be called "directories" as both a directory
and a jar file can be provided. A directory with `/*` would also load
all the jar files from that directory.
The "directories" property has been deprecated as a result.
Closes gh-35179
Previously, we tried to prevent spring-boot-docker-compose from
causing problems with AOT and native images by excluding it from
the AOT processing classpath. This allowed AOT processing to
succeed. We cannot apply the same exclusion to the native image
classpath so spring-boot-docker-compose was still included in the
native image. This results in a failure at runtime due to missing
reflection hints.
This commit reverts that changes that excluded
spring-boot-docker-compose from the AOT processing classpath. This
allows AOT processing to generate reflection hints but reintroduces
the failure caused by the connection details bean definitions using
an instance supplier callback. To overcome this problem we disable
DockerComposeLifecycleManager during AOT processing and in a native
image. This ensures that no attempt is made to call docker compose up
and no connection details beans are defined.
Fixes gh-35676
When excluded from the AOT processing classpath, a reflection hint
for DevTools' RestartScopeInitializer that's registered in
spring.factories is not generated. When the native image is compiled
we have no control over its classpath so DevTools is included. This
causes a failure at runtime as RestartScopeInitializer cannot be
loaded due to the missing reflection hint.
Until we have control over the native image classpath, we need to
include DevTools on the AOT processing classpath and then rely on
DevTools disabling itself in a native image which it already does.
Fixes gh-35853
This commit also disables the creation of forward merge issues
when merging into main. Forward merge issues will be re-enabled
once 3.1.1 has been released.
An `applicationDirectory` option on the Maven
`spring-boot:build-image` goal and the Gradle `bootBuildImage` task
can be configured to set the location that will be used to upload
application contents to the builder image, and will contain the
application contents in the generated image.
Closes gh-34786
