As I'm a big Maven n00b I'm wondering how to exactly 'run' this command. Is this done in Eclipse? On the command line?

You could use either. I do most of my maven work from the CLI. With maven 2 installed, it is run using 'mvn <target>'. Here's an intro to the maven lifescycle:

http://maven.apache.org/guides/introduc ... cycle.html

Basically a 'mvn package' will build and test the code, then package it into a jar (or war, in the gwt case).

If you added the IAM plugin to eclipse (on wiki:Using_Svn), then you can right click on the project, select 'Maven 2'->'m Package Artifact', and it will do the same thing.

I see it creates a file in trunk\ted-core\target\. The only problem is that this file doesn't do anything (even when placed in the runnable ted folder.

I'll take a look at this tonight.

I'm @ work right now.

Do I check-out ted-core or just the whole trunk when I want to work on ted?

If I check-out ted-core I get all kinds of errors (I think the dependencies are not checked/downloaded), if I check out the trunk, I cannot specify a run-configuration to launch tedMain...

I think you've to check out the whole trunk and then only add ted-core as a new project into Eclipse.

This means that you can't check out the trunk in the eclipse workspace as ted-core then no longer is a direct subfolder of the workspace (or some error like that which eclipse doesn't like).

As Jofo had mentioned, you have to check out trunk.

ted-core has its own eclipse project.

In the ted-core directory, run to get maven to pull down all dependencies. Then load your project into eclipse.
