> Project: Maven Checkstyle Plugin
> Issue Type: Bug
> Affects Versions: 2.12.1
> Environment: Apache Maven 3.2.1
> (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T18:37:52+01:00)
> Maven home: /usr/local/Cellar/maven/3.2.1/libexec
> Java version: 1.7.0_51, vendor: Oracle Corporation
> Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre
> Default locale: en_US, platform encoding: UTF-8
> OS name: "mac os x", version: "10.9.2", arch: "x86_64", family: "mac"
> checkstyle plugin version: 2.12.1
> Reporter: Marcus Höjvall
> Priority: Critical
>
> I'm getting a NullPointerError when running:
> {code} mvn clean compile -Pall {code}
> And all is a profile running the checkstyle plugin. This however works if I
> run install instead of compile, like this:
> {code} mvn clean install -Pall {code}
> Compile however works good when running it on a submodule but not on the root
> module.
> I don't know how to proceed and maven told me to contact the plugin
> maintainers through this link:
> https://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException
> Please let me know if there is anymore information that I need to provide or
> other ways to help out
