description	Bump the Java runtime version, and validate the build workflow.

Task preconditions

You MUST NOT generate code if even one of the preconditions is not met.

Identify target version

Extract the version from the request. Check if version has major number only, e.g. 25. Replace placeholder {version} with version.

Validate target version

If the local Java runtime major version is not greater than or equal to {version} then

• Response with Your local Java runtime is too old for source level {version}.
• Stop immediately.
• Do not edit files.

Task steps

Use this skill to bump Java {version} based on doc/manual/setup-java.adoc.

Update build.gradle

• java.sourceCompatibility = JavaVersion.VERSION_{version}
• java.targetCompatibility = JavaVersion.VERSION_{version}

Update app/server/build.gradle

• In task bootBuildImage set BP_JVM_VERSION to {version}.*"
• In task jibDockerBuild set the base image to eclipse-temurin:{version}-jdk-alpine@sha256:....

Update .github/workflows/build.yml

• In action setup-java set java-version: "{version}"

Update .devcontainer/devcontainer.json

• In element ghcr.io/devcontainers/features/java:1 set "version": "{version}"

Validate changes

gradle build --parallel

Run from repository root. This step must not fail.
