CodenameOne stopped working after build

Question

I have an odd issue with codenameone, and I'm not even sure what went wrong. I've tried to "send windows phone build", and don't think I have changed anything else since then. However, after I did so the simulator wouldn't launch and kept saying my imports were wrong. They weren't, the suggested solution was importing once that were already in.

The errors I get

All the classes he can't find are actually in my solution, I already tried re-adding them to the build path. Any suggestions?

That is odd.

First check that you indeed still have the package com.mycompany.myapp where you have the public class MyApplication. Do a clean build of the project and see if this class makes it into the jar file under the dist folder.
