[jira] [Created] (SPARK-14867) Make `build/mvn` to use the downloaded maven if it exist.

-------------------------------------

             Summary: Make `build/mvn` to use the downloaded maven if it exist.
                 Key: SPARK-14867
                 URL: https://issues.apache.org/jira/browse/SPARK-14867
             Project: Spark
          Issue Type: Improvement
          Components: Build
            Reporter: Dongjoon Hyun
            Priority: Trivial


Currently, `build/mvn` provides a convenient option, `--force`, in order to use the recommended version of maven without changing PATH environment variable.

However, there were two problems.
- `dev/lint-java` does not use the newly installed maven.
- It's not easy to type `--force` option always.

If we use '--force' option once, we had better prefer the Spark recommended maven.

This issue makes `build/mvn` check the existence of maven installed by `--force` option first.
