The problem has appeared Eclipse 2019-09. I write some code without any problem. Sometimes, I write code and press ctrl+space and eclipse halting and not responding. How i can I solve this problem?
Edit: I found this error in eclipse log;
!ENTRY org.eclipse.m2e.logback.appender 2 0 2019-10-14 13:44:08.997 !MESSAGE Failed to download org.eclipse.recommenders:index::zip:0.0.0 !STACK 0
Edit 2: I found 'Code Recommenders' cause this error. reinstall eclipse and jboss tools without recommenders. solved the problem !
