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.
Closes gh-34786
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.
