After importing into Intellij (ensuring I import the pom.xml). Setting up the runner via Edit Configuration. I then go to the command line and run mvn compile on graylog2-server. When I go back into intellij and click run. I get a bunch of errors dealing with `RuleLangParser`. They are in the pipeline-processor-plugin. How can I fix the error!? It seems it has been replaced with PipelineRuleProcessor.

If you’re using [graylog-project](https://github.com/Graylog2/graylog-project), you’ll have to build the complete project _at least once_ from the root project (which in turn builds all the submodules such as `graylog2-server` and the plugins).

Yes I am using the graylog-project. I navigated to graylog-project-repos/graylog2-server. That is where I have been running `mvn compile`. I get success… it is when I load up the project into intellij and click run that I get these errors.
