Content Assist (Ctrl + Space) Is Not Working – Eclipse

Problem

Content Assist (Ctrl + Space) is not working in my Eclipse IDE version 3.3. I have two Eclipse IDE installed, both in my laptop and personal desktop computer. However my laptop Eclipse 3.3’s content assist feature is working perfectly, but not my personal desktop computer. Every time, when i pressed on the Ctrl + Space combination keys, Eclipse just show me nothing…it’s drive me crazy. How can such a killer feature is disabled in my Eclipse IDE !!!?

I start Googling online, this problem is happened since Eclipse IDE version 3.2, many people suffer and many solutions come out to quick fix on it. Sadly, there is no final solution for it, some may work and some may not.

Solution

Here i summarized few solutions that may fix it.

1. New Project WorkSpace

Create a totally new workspace and import your existing project. Remember check “Copy projects into workspace” to copy all your existing work to new workspace.

2. Content Assist Configuration

Configure Eclipse’s content assist, go “Preferences>Java>Editor>Content Assist>Advanced“. Make sure “Other Java Proposals” is ticked

3. No Hijacked

Make sure (Ctrl + Space) combination key is not hijacked by other application. For examples, My desktop computer (Ctrl + Space) combination key is hijacked by my Windows text input feature. I enabled it for Chinese and English language, one of the text input combination key is using (Ctrl + Space), so, conflict happened.

3. Regional and Language Options

Make sure “regional and language options” is in English language. For example, Windows, Control panel –> Region and language options –> Advance tab –> Language for non-unicode program –> Make sure English (United States) is selected, others may not work, no idea why like this, but it worked.

“Follow him on Twitter, or befriend him on Facebook or Google Plus.”

Can you change it to “Follow me…” this statement alone is in third person context 🙂

Thank you for your good solutions (as always). I also had a problem with referenced Maven Project. Types from the referenced project were missing. I just closed and opened this project 🙂

Thanks, this fix is still working for Eclipse SDK:

– Window > Preferences > Java > Editor > Avanced

– I set ticked the following (I’m not sure which one did the trick):

>> Java Non-Type Proposals

>> Java Proposals

>> Java Type Proposals
