I'm trying to write a plugin and I'm following steps (here) for downloading Idea source and building. I'm stuck in two places. First, the docs say to use JDK 1.6 but I'm on a Mac running El Capitain. It's next to impossible to find/install JavaSDK < 1.7. Can a later JavaSDKbe used instead? Next, I've opened the project and it complains that 39 modules cannot be loaded because of missing .iml files. It looks like many of these are Android modules. Should/can I safely ignore these errors and remove the modules from the project? Thanks in advance!
