NBnotify lets NetBeans IDE unintrusively tell you when things happen, while using other applications. This NetBeans plugin provides integration with Growl on OSX.
This plugin is Intel-only: compiled on a MacBook Pro running Snow Leopard.
Most likely does not work with the Growl found in the Mac AppStore.
Just make sure Growl runs on your system and the plugin will use it. No need to configure anything – install and forget about it.
The plugin will automatically register an Auto Update center with your IDE so when NetBeans is looking for updates, it will also pick up NBnotify updates.
Since NBnotify just posts the IDE messages, you’ll see everything in the language of your IDE.
