Eclipse doesn't autocomplete and find references anymore
Solution 1:
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.
Solution 2:
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
