issue with the code completion in Scala IDE for Eclipse

I'm using "Eclipse for Java Developers 7.2" and Scala IDE 2.1.0. The issue is "code completion"...

I have "Use Scala-compatible JDT" and "Enable JDT content assist" enabled under my Eclipse. Are there any other options I shuold turn on?

Solution

Finally I got luck to solve this.

The reason behind why this happens is because eclipse stores a .metadata file in , which acts as a cache to load auto-complete suggestions.

If you try Project->clean, and then try the auto-completion the required java class members can be found in auto complete suggestions.

So the SOLUTION IS: go to your eclipse.ini, in case of mac located at: /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini

and add "-clean" in the ini file just before "-project".

This has a down impact of that now your eclipse might take a minute or two longer to start for the first time. But for me , it was acceptable.
