Failed to start sample playn project - compile errors

I tried to follow the instructions on the getting started page for playn and run into problems when starting the first java showcase program. I get the following errors when I right-click and run the Maven test. I also get numerous errors on the eclipse problems tab related to (failure to transfer xxx from yyy), where xxx is some jar file and yyy is the gwt or playn website

You can try the following:

Right click on "playn-showcase", then: Run As -> Maven Install

He must correctly get all the dependencies.

The next time you want to run the sample, you can follow the training procedure:

Right click on "playn-showcase-java", then: Run As -> Maven Test
