Re: [jdt-dev] compiling for first time

Thanks for the responses, I ended up going the Oomph route, which worked -- I now have JDT imported into Eclipse (with no errors in the problems tab!).

But I'm not clear how the general build/test development cycle works.  Is there a way to run my jdt ui code changes within the same running Eclipse instance, or do I need to instead build an artifact, perhaps via cmd-line maven, and then run that artifact as a separate Eclipse instance to see the changes?  What's the actual development flow people use when writing code?

Try building like follows

I'm a developer looking to fix a few bugs of personal interest to me in eclipse.jdt.ui.

I don't understand how to build the project.  I cloned this repo git://

and followed its README instrux, which fail at this command:

    mvn clean verify  -DskipTests=true

which yields the error at bottom of this email. 

My questions:
1) how to build/run the project
2) are there general instructions for new devs like me?  I was following this which didn't mention the aggregator pom at all, so maybe I'm building the wrong thing altogether?

Many thanks

Here are the error details:
