Thank you for your feedback

It seems that the method com.intellij.openapi.module.Module.getModuleFile() returns null!

I did all my tests in a maven project so each module has a pom.xml and getModuleFile() never returned null. Can you tell me more about your project?

How is it built? What is its structure? I would really appreciate a light sample

Regards Philippe

I also experience the same NPE. My project is multi module gradle project, and structured as follows:

/root
   /api
      build.gradle
      /src
         /main
         /test
   /service
      build.gradle
      /src
         /main
         /test
   build.gradle

Hope this would help.

It's a great plugin, anyway!

OK Would it be possible for you to send me a small sample that reproduces the problem?

In order to generate the plantUML diagram, my code relies on Idea APIs.

Regards, Philippe

Same NPE for me. I just downloaded plugin and did "Tools -> Sketch It!" inside a class.

BTW This is a very cool plugin in perspective. Hope you fix it.

Same issue here with a Gradle project.

Creating a skeleton pom.xml with only the GAV properties fixed this issue temporarily - but only for generating the top-level class diagram (module). Generating a diagram for a package or a class in a package yields the same exception even with that POM present.
