This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
There is support for NetBeans and IDEA 9 already. Eclipse does not have specific support yet, however you can open a Griffon project as a regular Groovy project and use Eclipse's Ant integration to launch griffon commands.
