Caused by: java.awt.HeadlessException: 
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I have added this

DISPLAY=:0.0
export DISPLAY

To /home/me/.bask_profile and /home/me/.bashrc also But all in vain. Help me, let me know why this error occurs.

Answer 1

The groovy console is a GUI app and it looks like you're trying to run it in an environment that doesn't support graphics, e.g. connecting to a remote machine via telnet/SSH.

A possible workaround is to use the Groovy shell instead of the Groovy console. The Groovy shell is functionally similar to the Groovy console, but the shell is a command-line, rather than a GUI app.

Assuming the Groovy bin directory is on your PATH variable, you should be able to run it by typing groovysh.

I had the same problem. And I had fixed it changing my firewall settings (used firestarter) that prevents some applications from accesing the x server
