             Summary: Use mvn in `dev/scalastyle`
                 Key: SPARK-30534
                 URL: https://issues.apache.org/jira/browse/SPARK-30534
             Project: Spark
          Issue Type: Improvement
          Components: Project Infra
    Affects Versions: 2.4.4, 3.0.0
            Reporter: Dongjoon Hyun


This issue aims to use `mvn` instead of `sbt`.

As of now, Apache Spark sbt build is broken by the Maven Central repository 
policy.

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.
