Eclipse doesn't autocomplete and find references anymore

Question

A few days ago I was using autocomplete features and Ctrl-click without any problem.

But now those features don't work anymore: the autocomplete shows up but is always empty, and Ctrl-click doesn't work because Eclipse doesn't recognize the classes anymore.

This doesn't even work for a class or function or variable in the same file, so I guess this is not a configuration problem, but maybe a cache that is corrupted?

Try this:

Go to Preferences » Java » Editor » Content Assist » Advanced.
Make sure Other Java Proposals is ticked/checked

If that does not work simply "close" the project and reopen it.

This was a tough one for me to solve (running Juno Version: 4.2.1 Build id: M20120914-1800 on Mac OSX 10.6.8).

The steps I had to take were:

Run Help » Check for updates and then restart to get to the most recent version
As noted above, Go to Preferences » Java » Editor » Content Assist » Advanced
Click everything Java related in both sections
Restart again

On ubuntu studio the ctrl-space was assigned at the operating system level to change the keyboard input method. I had to change the Next Input Method in Settings Manager–>Keyboard Input Methods–>Next Input Method field.

I changed it from ctrl-space to ctrl-alt-shift-space.
