[jdt-dev] compiling for first time

[Ari Kast <arikast@xxxxxxxxx>]

Hi 

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://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.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 https://wiki.eclipse.org/JDT_UI/How_to_Contribute#The_Build which didn't mention the aggregator pom at all, so maybe I'm building the wrong thing altogether?

Many thanks

Ari
