A manifest entry `Spring-Boot-Native-Processed: true` is added to the
jar manifest by the Maven or Gradle plugin when the jar has been built
for use in a native image. With the Gradle plugin, this is done in
reaction to the GraalVM Native Image Plugin being applied to the
project. With the Maven plugin, this is done when the `native` profile
is applied to the build.
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.

A `createdDate` option on the Maven `spring-boot:build-image` goal
and the Gradle `bootBuildImage` task can be used to set the `Created`
metadata field on a generated OCI image to a specified date or to
the current date.
Closes gh-28798
Update logic in `BootZipCopyAction` to align with the recent changes
made in the Maven plugin (commit 998d59b7). Timestamps are now
specified in UTC and offset against the default timezone before being
written.
Removing the offset from our UTC time before calling `entry.setTime()`
ensures that we get consistent bytes in the zip file when the output
stream reapplies the offset during write.
Closes gh-21005
This commit adds a `Build-Jdk-Spec` attribute to the manifest in a
jar or war file built with the Spring Boot Gradle plugin. This
aligns the Gradle plugin's behavior with the default Maven plugin
behavior.
This removes the need to set a `BP_JVM_VERSION` environment variable
when invoking Cloud Native Buildpacks, as the Paketo buildpacks will
honor `Build-Jdk-Spec` in a jar or war manifest to determine the
default JVM version.
Fixes gh-32829
Update the Maven and Gradle plugin to generate an `argfile` file
file under `META-INF/native-image` that contains `--exclude-config`
arguments that should be passed when generating a native image.
The contents of the file is generated for each nested jar that has a
`reachability-metadata.properties` file containing 'override=true'.
The `reachability-metadata.properties` file is expected to be generated
by the Graal native build tools plugin.
Closes gh-32738
Previously, the AOT source sets were not created until both the
Java and Spring Boot plugins had been applied. This could create
ordering problems when the Spring Boot plugin's native image plugin
action tried to access the AOT source sets to configure the
classpaths of the nativeCompile and nativeTest tasks. If the
plugins were applied in a particular order the AOT source sets
would not exist and a failure would occur.
This commit updates the Spring Boot AOT plugin to create the source
sets as soon as the Java plugin has been applied. This ensure that
they're in place when reacting to the native image plugin being
applied.
Closes gh-32661
