> This issue aims to use `mvn` instead of `sbt`.
> As of now, Apache Spark sbt build is broken by the Maven Central repository policy.
> - https://stackoverflow.com/questions/59764749/requests-to-http-repo1-maven-org-maven2-return-a-501-https-required-status-an
> > Effective January 15, 2020, The Central Maven Repository no longer supports insecure
> > communication over plain HTTP and requires that all requests to the repository are 
> > encrypted over HTTPS.
> We can reproduce this locally by the following.
>     $ rm -rf ~/.m2/repository/org/apache/apache/18/
>     $ build/sbt clean
> This issue aims to recover GitHub Action `lint-scala` first by using mvn.
