Walkthrough

Adds a GitHub Actions workflow for Maven builds on pushes and pull requests targeting master. The workflow sets up Temurin JDK 17, caches Maven dependencies, runs the package build, and submits the dependency graph.

Changes: Maven CI

Layer / File(s)	Summary
Configure Maven build and dependency submission .github/workflows/maven.yml	The workflow checks out the repository, sets up Temurin JDK 17 with Maven caching, runs mvn -B package --file pom.xml, and submits the Maven dependency graph. It runs on pushes and pull requests targeting master.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: Moderate · up to 41bcf

The new CI workflow is likely to fail on its Maven build because it uses JDK 17 for a Java 21 target. It can also fail on fork pull requests during dependency submission. Fix the JDK version and scope the job's token permissions before merging.

Architecture risk: Low · up to 41bcf

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

Architecture concerns

Before / after behavior

• observed — Modified behavior in .github/workflows/maven.yml: Adds a GitHub Actions workflow that builds the Maven project on pushes and pull requests to master, using Ubuntu, Temurin JDK 17, and Maven dependency caching. It then runs the package build and submits the dependency graph with a pinned action.

Full details: Title check

Explanation

The title "Review do PR upstream #1407" is vague. It does not name the change. The PR adds a Maven CI workflow (.github/workflows/maven.yml) that builds on pushes and pull requests to master, sets up JDK 17, caches dependencies, and submits the dependency graph. The title is Portuguese for "Review of upstream PR #1407" and gives no information about the workflow. The objectives say the PR is a copy of google#1407, but the title does not describe the actual changeset.

Resolution

Rename the PR to describe the main change. For example: "Add Maven CI workflow with JDK 17 and dependency graph submission". If the title must reference upstream PR #1407, add that reference after the descriptive text.

supports the project’s Java 21 target, so Maven can compile and complete the
build.
- Line 35: Move the dependency submission action out of the pull-request build
job into a separate job that runs only for push events and explicitly grants
contents: write. Keep pull-request builds read-only and ensure they do not run
dependency submission.
- Line 23: Restrict permissions for the build job to the minimum required and
set checkout’s persist-credentials option to false so Maven plugins cannot
access a persisted job token. If the dependency-submission step requires write
permissions, move it out of the build job into a separate job with only the
permissions it needs.

The build job runs Maven plugins with a checkout token that is not restricted.

actions/checkout@v4 stores the job token in the Git configuration unless persist-credentials: false is set. The build job declares no permissions: block, so that token gets the repository default scope. Line 31 runs mvn package, which executes third-party plugins. A compromised plugin can read the persisted token. If the repository default grants write access, the plugin can write to the repository. The dependency-submission step at lines 34-35 runs in the same job after the build.

Declare least-privilege permissions for the build job. Disable credential persistence in checkout. If the dependency-submission step needs write access, move it to a separate job that declares its own permissions.

Use a JDK that supports the project's Java 21 target.

At the reviewed revision, pom.xml Line 82 sets java.version to 21. Lines 183–184 use that value for compiler source and target settings. JDK 17 cannot compile this target, so the Maven build fails before completing the tests or package. Configure a supported JDK instead. (raw.githubusercontent.com)

Exclude fork pull requests from dependency submission.

When a fork pull-request build succeeds, this unconditional step attempts dependency submission. Fork tokens normally have read-only permissions, but the submission endpoint requires contents: write. The request therefore fails and makes the build job fail. (docs.github.com)

Run submission in a separate push-only job with explicit contents: write. Keep pull-request builds read-only.
