Intellij IDEA 14: Error Loading Project: Cannot load module cars-service

Question

With my last restart of my mac I had a problem with IntelliJ IDEA project : the .iml file was deleted and I have

Error loading project: cannot load module cars-service Details ....

in the console.

Besides that, the structure view of the project has disapeared. Here is a screenshot:

Answer 1

Finally, I imported my project via import project so the iml file was recreated.

Answer 2

Closing intelliJ. Deleting the .idea folder and re-opening intellij worked for me.

Answer 3

This happened to me this morning*, and fortunately there's a fairly straightforward solution.

1. Press Ctrl+Alt+Shift+S (or go to File > Project Structure...) and click Modules on the left of the window.
2. Click the green + above the list of modules then New Module. Select the type of module (Java, Android, Flash, what have you) and click Next.
3. Enter the details of the lost module. Click the browse button to the right of Content Root and navigate to the directory that contains your lost module. The module name will be populated with the directory name by default, but you can rename it without issue.

(*I... got a bit gung-ho with the old git clean -fd. I don't recommend it.)
