I've just set up a recent version of Eclipse and if you make a project a Maven project it is possible to run the Maven build from Eclipse. I haven't explored this in depth yet. By default Eclipse just compiles the modified classes when you save them and does not run a full build, maven or otherwise.
It is possible of course to use remote debugging which has the benefit of giving you an environment that is closer to what end users see. I also see Gary's point of wanting the convenience of being able to quickly run JUnit tests from the IDE without going through an 5-8 minute build for every minor code change... I still think configuring the "packages" attribute in the test config files gives you the best of both worlds... On Sun, Jun 1, 2014 at 3:37 PM, Ralph Goers <[email protected]> wrote: > I'm confused.
