Project tree shows confusing directory structure

IntelliJ shows a confusing picture of the directory structure in the project tree pane.

• Example 1 The following directory tree

  src
  ├── main
  │   ├── resources
  │   └── scala
  └── test
      └── scala
  

  is shown like this:

  

  I.e. the test directory is omitted, and it is not obvious where the lower scala folder belongs to. I would expect the project tree to match the actual directory structure.

• Example 2 The following directory tree

  src
  ├── main
  │   └── scala
  └── test
      └── scala
  

  is shown like this:

  

  I.e. the main and test directories are omitted. It is not obvious where the two “floating” scala folders belong to. I would expect the project tree to match the actual directory strucuture.

I don’t think it’s a bug in IntelliJ. The issue is that the root folder is added as a Source Folder in Intellij. This means IntelliJ interprets every sub-folder as a java-like “package”. Removing the root folder from the module setup manually yields the expected results:

Notice that this also changed the icons for the folder src and main, as they are now regarded as normal directories rather than java-like packages.

Sounds great, thanks!
