I'm trying to build the devel version with the 'preconfigured' eclipse environment. However even asking for a clean it says:

Downloading: http://repo.maven.apache.org/maven2/org ... -2.4.0.pom

[ERROR] Plugin org.codehaus.mojo:gwt-maven-plugin:2.4.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.codehaus.mojo:gwt-maven-plugin:jar:2.4.0: Could not transfer artifact org.codehaus.mojo:gwt-maven-plugin:pom:2.4.0 from/to central (http://repo.maven.apache.org/maven2): Connection refused: no further information to http://repo.maven.apache.org/maven2/org ... -2.4.0.pom -> [Help 1]

I can't in fact access the mojo.codehaus.org site mentioned in the pom file (please note that I don't know a thing about maven or eclipse building stuff...)

Is that fixable, a misconfiguration o just me unlucky and the repository being down?
Thanks in advance

We has some issue with our maven repository maven.openkm.com that might solve the issue. First time I suggest compilation from command line and not from eclipse, I observated - not always - eclipse have problems for initial downloading maven artifacts. You can also try to clean your local maven repository, sometimes some artifact it becomes corrupted and messages are not indicating what really it is happening.
