Exception in thread "main" java.awt.HeadlessException: Unable to detect graphics environment
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

解决办法：

If you're on the main display, then export DISPLAY=:0.0 or if you're using csh or tcsh setenv DISPLAY :0.0
