Eclipse Open declaration in Java project

Question

In an Eclipse SVN project I have a problem; when I tried to open a declaration of one class, I got this error:

Problems opening an editor Reason : projectna         


        

Answer 1

I had the same in Eclipse Luna on Debian 8. I was missing the .classpath file when checking out from SVN. I manually copied it and changed some path names, refreshed the project and it was working again.
