Intellij unable to build java project with manifold-preprocessor

When building application using manifold preprocessor through intellij it gives out null reference, consequently if you compile the application using “mvn compile” it compiles fine. Due to which unable to debug the application

To Reproduce Steps to reproduce the behavior:

1. Create simple java maven project (e.g maven-archetype-quickstart)
2. Modify pom.xml using the following link https://github.com/manifold-systems/manifold/tree/master/manifold-deps-parent/manifold-preprocessor#Maven
3. Now build application from intellij

@rsmckinney, Thanks for your time and help, it works now. It seems that there was some issue with configuration of Intellij, removing the configuration from %APPDATA%\Roaming\JetBrains fixed it. I’ll let you know if I narrow it down.

Thank you.

@rsmckinney thank you will try to run sample project provided by you.
