You can define a keyboard shortcut or even a toolbar button or menu item that will trigger any Ant target.
- Open build.xml and add your custom Ant target.
- When build.xml is open, you can see the list of all targets in the Navigator or Files windows.
- Right-click any of these targets and select Create Shortcut. A wizard appears that lets you configure your shortcut. For instance, you can also add a menu item or a toolbar button for the Ant target.
Each time you invoke the shortcut, the corresponding Ant target is executed.
