Eclipse “this compilation unit is not on the build path of a java project”

Question

I can\'t get autocompletion to work on Eclipse.

I\'m working on the project on svn. I set up project in Eclipse by going into

File -> Import -> Checkout As

Answer 1

I did copy the .classpath and .project from another project and adjusted the values properly.

Close the project before editing those files, when you are sure they reflect the reality (your reality anyway), re-open the project in Eclipse.

The workspace is rebuilt and all should work from then on.
