yew1eb opened a new pull request, #3880: URL: https://github.com/apache/celeborn/pull/3880
### What changes were proposed in this pull request? Each job in `maven.yml` re-downloads the Maven distribution from `archive.apache.org` via `build/mvn` (~25s typical, 1m49s observed on a slow network), even though `~/.m2` is already cached by `setup-java`. This PR adds an `actions/cache@v4` step for the extracted Maven install under `build/`, so `build/mvn` reuses the cached binary — its `install_app` already skips the download when `apache-maven-<version>/bin/mvn` exists. This mirrors the sbt launcher caching added for `sbt.yml` in CELEBORN-2432. ### Why are the changes needed? Save ~25s–2min per job; ~10–40 minutes of total machine time per CI run. ### Does this PR resolve a correctness bug? - [ ] Yes ### Does this PR introduce _any_ user-facing change? - [ ] No ### How was this patch tested? Verified locally that `build/mvn` skips the download when `build/apache-maven-<version>/bin/mvn` is present. CI on this branch shows the cache step restoring and no `curl` download of the Maven tarball. -- This is an automated message from the Apache Git Service.
