Android : eclipse ADT stack at 30% building workspace. Clean and build is not working

my eclipse ADT is suddenly freezing after building workspace 30% with no additional information. I already tried to switch workspace and import only google play library and a simple project, but it still stops in building workspace. Already tried to -disable automatic build -> clean all projects -> build all projects after clean

and it still stucks at 30%. Can anyone give me hand in this?
