playn not playing with mvn, ironically

Question

Trying to run the basic examples given by playn, wanting to have a go with the toolkit. I'm following the instructions as given here: http://code.google.com/p/playn/wiki/GettingStarted

However, after doing a clone and running mvn compile exec:java from the command line it comes up with the following response:

mvn compile exec:java

Totally lost now. I've taken a look at the help pages given, but they're just talking another language to me, it seems. Being a complete starter to both Maven and playn, I'm all over the place. HELP!

Cheers :)

EDIT:

After a pull and following instructions below, the following error comes up:

I also try in the core, and get the following error instead:

Still kinda lost. Any ideas?

The error in each case says that Maven could not find a related POM. Have you validated that? Have you tried invoking Maven with the `-e` and `-X` flags as suggested? — Sri Sankaran, Nov 12 '11 at 11:05
Somehow, running it with -e -X made the whole thing work. Not sure how stack tracing would have fixed it, but there you go! — David Archer, Nov 12 '11 at 12:13

We've just updated the way the Java backend is invoked via Maven. You should check out the latest GettingStarted instructions on the PlayN wiki.

However, this should also solve your problems:

cd playn-samples
git pull
cd showcase
mvn test -Ptest-java

Have you try doing a clean install

git pull
mvn clean install

might work

Try the Eclipse instructions for MVN. I tried them, and as of a couple of days ago, everything is working flawlessly.

Do you get an error with code completion on Eclipse ? I followed the same instructions and having errors now. – yasith Mar 14 '12 at 23:12
