Creating Netbeans project for ImageJ+my plugins friendly to upgrades

[Josh Doe-2]

Hello,
I maintain a dozen or so plugins for the folks I work with. I've just been
using Wordpad+Ant to write and compile my scripts. However, I have missed
code completion and debugging capabilities greatly. I've decided it's time
to start a proper Netbeans project.

I followed the tutorial over at
http://rsb.info.nih.gov/ij/developer/NBTutorial.html which helped a great
deal. The problem is that I'd like to keep my code and ImageJ's code
separate. So what I've tried to do is create two projects, one for ImageJ as
described in that article, and another based on my own Ant build.xml script.
However, Netbeans won't let me add the ImageJ source package folder to my
plugins project.

How can I be able to compile both ImageJ and my own set of plugins in
Netbeans, preferably simultaneously? When a new version of ImageJ comes out,
can I simply unzip the source and recompile? What if the build.xml script
changes?

Thanks all for any advice. If it's easier to do what I want in Eclipse, I'm
open to trying that.
