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.

That did the trick thank you ! I am using Eclipse for PHP, so I tried closing and reopening the project and it worked. Exactly what I was looking for thanks. – Matthieu Napoli Nov 11 '10 at 16:54

Kepler didn't have this turned on by default when I downloaded it for some reason – Jherico Jun 25 '13 at 21:59

+1 same thing. Kepler didn't have this turned on by default. Hopefully other people will come by and see this fix. ( Eclipse Kepler Turn On Content Assist AutoComplete Intellisense) – Daryl Teo Jul 06 '13 at 04:52

I dunno why Kepler doesn't have this on by default. That's a must for android dev. – noob Sep 20 '13 at 09:22

close/reopen worked for me. – simplfuzz Jun 05 '14 at 11:18
reopening the project worked...you are a genius! – Sumit Jain Jun 13 '14 at 09:28
Luna Release (4.4.0) - Modifying the preferences didn't appear to do anything for me. Closing/reopening didn't work either. I ended up deleting/re-adding the project and that worked. – user110857 Feb 26 '15 at 20:45
Same solution worked for System Workbench stm32. – PraveenMax Jun 21 '17 at 15:25

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.

Thank you. I don't know who designed this but the choice of ctrl+space to change the keyboard input method is really dumb. – benji Aug 15 '16 at 23:29
this is solution is also applicable for Mac Os. go to System Preferences > Keyboard > Input Sources and untick that stupid control-space binding. – Kerem Baydoğan Apr 02 '18 at 22:46
