> 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.
> --------
> According to [~srowen]'s comment, now this issue aims to remove `--force` option by auto-detection of maven version.
