Using both Eclipse and NetBeans on the same project

Question

Create your GUI with Netbeans. copy a Eclipse .project file (like below) into the project folder change the MyProjectName. Open Eclipse and import the project into your workspace, so you can open the projekt from your Eclipse workspace with Netbeans. Now you able to use Netbeans to create and change the GUI and editing the code with Eclipse.

MyEclipse offers an integration of the Netbeans GUI editor (Matisse) with Eclipse.

Echoing @Tom I'd use an external build tool (Maven 2 would be my pick). I've done this on projects before and as long as you don't walk all over Eclipse's .Xxxx files and folders you'll be fine. Then you get the full power of Netbeans (which integrates with Maven 2 really nicely) or Eclipse and also have the added value of an external build which can also be run by your CI tool. Everybody wins!

Cloud Garden makes a GUI editor called Jigloo that is quite nice if you are into that sort of thing (and the price is very, very reasonable). If that's all that's missing for you from Eclipse, I'd recommend that you take a look. Netbeans does a ton of stuff with source code that you aren't allowed to edit, etc...

One other thing that I will mention: I have used GUI editors like Matisse and Jigloo for super rapid prototyping. However, within 3 or 4 iterations, I always find myself dropping back to hand coding the layouts. I also find that when I'm doing rapid prototyping, I am almost always more productive when I change the layout manager to absolute and just place components. Once the design starts the gel, implementing the design by hand coding using a good layout manager (I strongly recommend MiG Layout) is pretty easy, and gives much better results.

I know that dragging and dropping a GUI layout is really enticing - but MiG Layout is incredibly productive for hand wiring GUIs, and I suspect that almost any developer will be more productive within a week going down that path.

import project in netbeans create gui and then again open the project in eclipse

it works with no error
