Problems Suring Content Assist After Installing WindowBuilder plug-in


The following message pops up when I try to use the content assist command (Ctrl+Space) after I installed the WindowBuilder plug-in :

"The 'API Tools Javadoc Proposals' proposal from computer from the 'org.eclipse.pde.api.tools.ui' plug-in did not complete normally..."

I already tried to de-select the API Tools Javadoc Proposals on Content Assist, as the program sugests, but still did not work. I also tried to select all the Java Proposals, tried to change the Key and nothing worked. I need to use this plug-in for a important project. Does anybody know what can I do?

PS: I never had this problem with Eclipse before, I uninstalled and installed the Window Builder plug-in to see what would happen, and the problem is definitely related to Window Builder.


Solution

  • Installing an older version of Eclipse could work, and indeed it does. I've installed Eclipse 2018-12 and the latest official (NOT prerelease) Window Builder version from the Eclipse Marketplace. Now the content assistant works fine.

    IMPORTANT: You can have more than one Eclipse installation at the same time on your computer, as long as it is in a different folder. That's how I did it at least. Bad thing is, that you'll probably need another workspace separate from your everyday workspace, just for the Eclipse 2018-12 installation.
