bump-gradle

name	bump-gradle
description	Updates the Gradle wrapper version used by this repository. Use when asked to upgrade Gradle, bump the Gradle wrapper, move the project to the latest Gradle release from the official release notes, run the Gradle build, and commit Gradle wrapper and dependency report changes separately.

Bump Gradle

Use the official Gradle release notes as the source of truth for both the latest version and the wrapper update command:

https://docs.gradle.org/current/release-notes.html#upgrade-instructions

Always check that page at task time. Do not rely on remembered Gradle versions.

Commit authorization

This skill is authorized to run git commit up to two times per invocation, under these constraints:

1. Gradle wrapper commit. Stage only the Gradle wrapper files (gradle/wrapper/gradle-wrapper.properties, gradle/wrapper/gradle-wrapper.jar, gradlew, gradlew.bat, plus files directly required by the wrapper update). Subject: Bump Gradle -> `GRADLE_VERSION` with the actual version substituted. Skip if no wrapper-owned file changed.

2. Dependency-report commit (separate from the wrapper commit). Stage only generated dependency-report files (docs/dependencies/pom.xml, docs/dependencies/dependencies.md). Subject: Update dependency reports. Skip if the build did not regenerate those files.

No git push, git tag, git rebase, git commit --amend, or any other history-writing operation. Those require a separate authorization (.agents/guidelines/safety-rules.md → Commits and history-writing). Do not create empty commits, and do not bundle unrelated changes into either commit.

Checklist

1. Work from the target repository root.

   Confirm ./gradlew and gradle/wrapper/gradle-wrapper.properties exist before changing anything. Inspect git status --short and preserve unrelated user changes. If Gradle wrapper files are already modified, inspect the diff and continue only when those edits are part of the same requested Gradle bump; otherwise ask before overwriting or staging them.

2. Read the latest Gradle version from the release notes.

   Open the Upgrade instructions section at the URL above. Use the version in the release heading and the wrapper command shown there. They should agree; if they do not, stop and report the mismatch.

3. Run the wrapper update command.

   Substitute the version from the release notes:

   ./gradlew wrapper --gradle-version=GRADLE_VERSION && ./gradlew wrapper
   

   For example, if the release notes say Gradle 9.5.1, run:

   ./gradlew wrapper --gradle-version=9.5.1 && ./gradlew wrapper
   

4. Run the build.

   ./gradlew clean build
   

   If the wrapper update or build fails, do not commit partial changes. Report the failing command and the relevant error output.

5. Commit only Gradle-related files.

   Inspect git status --short and git diff --name-only. Stage only files created or updated by the Gradle wrapper bump, normally:

   gradle/wrapper/gradle-wrapper.properties
   gradle/wrapper/gradle-wrapper.jar
   gradlew
   gradlew.bat
   

   Include other Gradle-owned files only when they are directly required by the wrapper update and are clearly part of the same change. Do not stage dependency reports or unrelated build output in this commit.

   Commit with the exact subject, replacing GRADLE_VERSION:

   Bump Gradle -> `GRADLE_VERSION`
   

   Example:

   git commit -m 'Bump Gradle -> `9.5.1`'
   

   If no Gradle-related files changed, do not create an empty commit; report that the wrapper was already current after verification.

6. Commit dependency reports separately when the build updates them.

   Stage only generated dependency report files. In repositories using this config, the usual paths are:

   docs/dependencies/pom.xml
   docs/dependencies/dependencies.md
   

   Include other changed files only when they are clearly generated dependency reports from the build. Commit them separately with:

   Update dependency reports
   

7. Verify the final branch state.

   Confirm the recent commit subjects and make sure no owned Gradle bump or dependency report changes remain unstaged:

   git log --format=%s -2
   git status --short
   

   Leave unrelated pre-existing user changes alone and mention them separately in the final response.

8. Ensure version.gradle.kts is bumped.

   Before this branch can be built or published locally, the project version must be strictly greater than the version on the base ref. Run the version-bumped skill — it is a no-op if a bump has already happened earlier on the branch, and otherwise uses the bump-version skill to perform the increment.
