[jira] [Commented] (SPARK-13085) Add scalastyle command used in build testing

["Charles Allen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-13085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15123946#comment-15123946 ] 

Charles Allen commented on SPARK-13085:
---------------------------------------

{code}
mvn scalastyle:check
{code}

was able to produce a similar error, but it is not obvious if that is the same command the build uses.

> As an occasional or new contributor, it is easy to screw up scala style. But looking at the output logs (for example https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/50300/consoleFull ) it is not obvious how to fix the scala style tests, even when reading the scala style guide.

> Scalastyle checks failed at following occurrences:
> [error] /home/jenkins/workspace/SparkPullRequestBuilder/core/src/main/scala/org/apache/spark/scheduler/cluster/mesos/CoarseMesosSchedulerBackend.scala:22:0: import.ordering.wrongOrderInGroup.message
> [error] (core/compile:scalastyle) errors exist
> [error] Total time: 9 s, completed Jan 28, 2016 2:11:00 PM
> [error] running /home/jenkins/workspace/SparkPullRequestBuilder/dev/lint-scala ; received return code 1
> {code}
> This ask is that the command used to check scalastyle is presented in the log so a developer does not have to wait for the build process to check if a pull request should pass scala style checks.
