HyukjinKwon opened a new pull request #30391: URL: https://github.com/apache/spark/pull/30391
### What changes were proposed in this pull request? This PR proposes: - Add `~/.sbt` directory into the build cache, see also https://github.com/sbt/sbt/issues/3681 - Move `hadoop-2` below to put up together with `java-11` and `scala-213`. - Remove unnecessary `.m2` cache. If you run SBT tests only, `.m2` directory is not necessary. - Use Java 8 in Scala 2.13 build. We can switch the Java version used for release later. - Add caches into linters. The linter scripts uses `sbt` in, for example, `./dev/lint-scala`, and uses `mvn` in, for example, `./dev/lint-java`. Also, it requires to `sbt package` in Jekyll build, see: https://github.com/apache/spark/blob/master/docs/_plugins/copy_api_dirs.rb#L160-L161. We need full caches here for Maven, SBT, and build tools. ### Why are the changes needed? - Remove unnecessary stuff - Cache what we can in the build ### Does this PR introduce _any_ user-facing change? No, dev-only. ### How was this patch tested? It will be tested in GitHub Actions build at the current PR ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
