Description

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.

========================================================================
Running Scala style checks
========================================================================
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

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.
