> Scalastyle config prevents building Maven child modules alone
> -------------------------------------------------------------
>
> Key: SPARK-6861
> URL: https://issues.apache.org/jira/browse/SPARK-6861
> Project: Spark
> Issue Type: Bug
> Components: Build
> Affects Versions: 1.3.1
> Reporter: Sean Owen
> Assignee: Sean Owen
> Priority: Minor
> Fix For: 1.4.0

>
> This doesn't work because scalastyle fails to run: {{cd core; mvn package}}
> It's something that might reasonably be expected to work, and does, except
> for scalastyle.
> scalastyle fails because its config file is declared to be at
> {{scalastyle-config.xml}}, but this is where it is relative to the project
> root (parent) only. The fix is to prefix with
> {code}
> ${project.parent.basedir}
> {code}
> And while I'm at it:
> It's a little funny that {{scalastyle-config.xml}} is at the top level of the
> project. It should probably live in {{dev/}} with other style-related
> resources. This requires updating the SBT config too.
> The current config writes output in {{scalastyle-output.xml}}, but, this
> means it ends up in the root directory of every module, where it's not
> cleaned up. It should go in {{target/}}.
> Regarding SPARK-4066, I also note that the config forces scalastyle checks to
> run in the {{package}} phase, when its default is the later {{verify}} phase.
> The complaint there was that running something like {{package}} during
> development with outstanding style problems fails the build. Just letting it
> default to {{verify}} would push back execution of scalastyle to cases where,
> say, {{install}} was run (or it was triggered manually).
> We can update Scalastyle to 0.7.0, to match the SBT build that actually runs
> these checks for real.
