Ok, this RubyMine has some serious issues. My day started out peaceful and then ended as a nightmare, courtesy of RubyMine. All I did was git checkout to a certain version of my repo. Well, when I did that, suddenly the folders in RubyMine disappeared. Yes, that is the first bug. I git checkout 8d4fbd1b5dfce0a3daa16896a603903a And then I open RubyMine and folders are gone! I closed and reopened. Still no folders. I restarted computer and still no folders.

I had to go to Project > File Structure and delete the Module. And then create a new Module. Now the project folders appear. But then I get this obscure error Rails server launcher wasn't found in the project. I have no idea what it means. I go online and they say delete .idea directory in your project. So I do that. And now again I have to delete and recreate the module.

This time it says "overwrite directory" since I have an existing project. I select "Yes" and then I open project and my secrets.yml is gone! Now I had to use secrets.yml I had backed up. And then finally it works.

Seriously, all this just because I wanted to checkout out a specific git commit? Come on.

UPDATE After further investigation, I understand what is going on. There are three critical Intellij Idea files with regards to the Ruby plugin:

/.idea/
MyProject.iml
/MyProjectGemset/

These three files should not be checked into git and should be consistent across the different branches of your project. You might have another *.iml in the project. Delete that and make sure you are using the same .iml throughout the branches.

These two files pertain to your SDK:

 MyProject.iml
/MyProjectGemset/

This file pertains to general configuration:

/.idea/
