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 support for Cloud Native Buildpacks builder platform
API 0.3, which is the latest platform API available currently. Support
for platform API 0.1 has been removed, adopting the policy of the pack
CLI to support the current platform API version and one version prior.
Fixes gh-20757
CNB builder images are now being tagged in a manner that indicates
the version of the platform API implemented. This allows Spring Boot
to default to a builder tag that guarantees API compatibility while
allowing for updates to bundled buildpacks.
Fixes gh-20171
This commit adds documentation for the configuration required to
use a remote Docker daemon with the `build-image` Maven goal or the
`bootBuildImage` Gradle task.
See gh-20538
This commit adds support for setting the image name and builder
parameters of the Gradle bootBuildImage task using command-line
options as an alternative to DSL configuration.
See gh-20520
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
With this commit, the Maven `spring-boot:build-image` goal and the
Gradle `bootBuildImage` task will configure the OpenJDK buildpack
to use the same JRE version as the project's target version,
provided the buildpack Java version is not explicitly set in the
build configuration.
Fixes gh-20172
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.
