Hi John,

I don't know anything about Scala, but as far as the incremental builder goes, you can create your own, along with a custom build.xml file that when it runs that can copy things to locations in different ways than what the standard incremental builder does. I had to do this to get a Java WebStart-based Java Client application to build correctly.

I know Chuck does something similar to get Eclipse to run tests and such automatically.

I'd say to go look at my instructions on the Wiki, but it appears that the confluence server is having problems.

Here's the basics (very D2JC-focused, but you should be able to take the concept and twist it to work for you): 

1) Create a new builder in your project properties (right-click on your project, select properties)

2) Point the builder at your new build.xml file (see attached for an example)

3) Set the refresh information:

4) Set the Targets (this is what tells Eclipse when to run your custom builder):

Can't help you with this one... sorry.

Good luck!
