Gui should start in background

[hohwille]

Actual behavior

Currently ide gui starts in foreground.
This blocks the current shell so after typing ide gui the GUI shows up but the terminal is blocked.
Only after I exit the GUI, I get BUILD SUCCESS message from maven and can continue using my terminal session.

Reproduce

ide gui

Expected behavior

The GUI should be launched in the background and my terminal session should be usable even while the GUI is running (just like IDEs such as Eclipse, Intellij, etc.).

Comments/Hints

The GUI should use ProcessMode.BACKGROUND to prevent this.
