"The 'org.eclipse.jdt.ui.JavaAllCompletionProposalComputer' proposal
computer from the 'org.eclipse.jdt.ui' plug-in did not complete normally.
The extension took too long to return from the
'computeCompletionProposals()' operation."

Eclipse was working fine till yesterday, not sure what happened today. Can

Does it now always happen? If so, did you follow the advice in the dialog?

Hi,

I searched but did not get any answers for the below problem.

I get the following when I press Ctrl+Space now in eclipse.

"The 'org.eclipse.jdt.ui.JavaAllCompletionProposalComputer' proposal computer from the 'org.eclipse.jdt.ui' plug-in did not complete normally. The extension took too long to return from the 'computeCompletionProposals()' operation."

Please help me.

Regards,
-Abhishek

Look at the <workspace>\.metadata\.log for any related messages. Also try to restart eclipse with eclipse -clean and see if you still get those problems.

This problem has plagued me for much longer than I would like to admit. Thank you Prakash for the advice on going to the log file to check out the errors.

I get a "Zip Exception: error in opening zip file" exception. My project has a very large collection of libraries, and I usually go to the directory which contains my libraries, and select them all, and add them to a projects library build path. In this process, I accidentally selected several .tar and .tar.gz files which happened to be in the same directory. Needless to say these .tar and .tar.gz files were causing the exception, and causing the super slow content assist. I deleted them, and removed them from my projects libraries build path, and low and behold, I again have a usable eclipse.

I had the same issue except that my libraries didn't include any zip files, but I was getting ZipExceptions when looking at the logs. Seems it was some of the Spring JAR files I had included in my project. I had copied them to a directory withing the project, then added them.

I solved my problem by moving the Spring JAR files to a directory external to the project & adding them to the project as external JARs.

As a side comment: kind of new to Java (& especially Spring) so not sure exactly what will happen if I tried to compile/deploy the project (will it pull the external jars into the compiled project, or try to find them externally??). At least I can work more effectively for the time being & cross that bridge when I come to it (moving them to be internal when I want to compile if I have to).
