Eclipse - Cancel "Convert to JavaScript project ..."

Question

I am working on an AngularJS / Gradle project in Eclipse. Everything worked fine, and no error was displayed in my project explorer.

Because of the idea, I selected my project -> right click -> Configure -> Convert to JavaScript project ...

After that, I had various errors in my * .js (AngularJS) files in my explorer project (but my project works fine!). Therefore, I decided to remove nature from my .project file, but errors still exist.

What is the correct way to "undo" that "Convert to JavaScript project"? Any help appreciated!
