building the Flex PMD source code

Hi, I looked at the developer documentation on how to build it locally at http://opensource.adobe.com/wiki/display/flexpmd/Developer+documentation .

When I run step 7: mvn package

I get this error

[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------

I have these versions:

Maven version: 2.0.10
Java version: 1.6.0_10

Does it need to be maven 2.2.0 or later or Java 1.5 or is there some other dependency I'm missing? The documentation doesn't mention the maven implementation flex-mojos so I am assuming that is not needed.

TIA,

Magnus
