i had this same problem. here is how i solved it.

in eclipse go to

window -> preferences -> java -> editor -> content assist -> advanced

and check the boxes labeled "java proposals" and hit apply.

this solved my problem. hope it helps.


i had the same problem and none of the solutions here worked. for some reason, my scheme had changed from "default" to "emacs". so to fix it, i had to go:

preferences> general> keys and change the scheme back to default.


eclipse use "ctrl+[space]" to show the "css/html/java proposal"


here's another solution i dicovered:

i would check the other solutions listed here first and if all else fails shut down eclipse then delete the file 'org.eclipse.jdt.ui.prefs' found in the workspace directory (workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings).

seems in my case the workspace became corrupted somehow and this fixed it. haven't yet noticed any adverse effects by doing this.


go to preferences > java > editor > content assist and paste "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz." (note the dot after z) into the "auto activation triggers for java:" field. this worked for me ! now as i type i get autocomplete options


im my case was api tools proposals the option that cause my autocomplete doesn´t work, here are the 4 default options that must be checked...

  • api tools proposals.

  • java proposals.

  • swt template proposals.

  • template proposals.

    default configuration

the next time i must be careful when click ctrl+space =d
