I am using Eclipse Mars in Kubuntu 16 and whenever i am trying to compile or even run a java program it doesnt do anything. It just shows its compiling but doesnt do anything even after an hour. Its only if I minimize the eclipse and then restore it then it works. I have uninstalled eclipse several times and still it is showing the same problem. I have tried several distros until I find KDE based distros and am really a big fan of it. I am unable to understand whether its eclipse fault or Kubuntu. Any Solution?
