This commit adds a `createdBy` structure to the metadata of the ephemeral
builder container image that identifies Spring Boot as the creator of the
image, along with the Spring Boot version.
See gh-20126
This commit upgrades the default CNB builder image from
cloudfoundry/cnb:0.0.43-bionic to cloudfoundry/cnb:0.0.53-bionic.
It also adds integration tests for the Maven and Gradle plugins
to verify both versions are supported.
Cloud Native Buildpacks platform API version 0.2 introduced
two breaking changes: the order of invoking the restore and analyze
phases was reversed, and the cache phase was removed in favor of
distributing caching across other phases.
This commit adds support for Cloud Native Buildpacks builders that
implement platform API version 0.2, while maintaining compatibility
with builders that implement Lifecycle version platform API
version 0.1.
Closes gh-19829
Previously, the image builder used by the build tool plugins ignored
errors from lifecycle phases and continued with subsequent phases.
This commit inspects the status of the builder container after each
lifecycle phase and aborts the image building process if the exit
status of the container after any phase is non-zero.
Fixes#19949
Rename the `spring-boot-cloudnativebuildpack` module to
`spring-boot-buildpack-platform` and update the the package
name to `org.springframework.boot.buildpack.platform`.
Closes gh-19851
