nuxeo mvn compilation issue

Question

I am trying to compile nuxeo using as a guide the documentation described here: http://doc.nuxeo.com/display/public/CORG/Getting+the+Nuxeo+source+code

However I am not able to run the following command sucessfully: mvn -DskipTests install -Paddons

I have no idea what can be wrong. Here are the details of my workstation:

java -version java version "1.7.0_17" Java(TM) SE Runtime Environment (build 1.7.0_17-b02) Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

The error has almost no information, so I am lost for a solution.

It seems Maven is not using the same Java as the one you configured in your environment:

java version "1.7.0_17"
Java version: 1.7.0_04, vendor: Oracle Corporation

That may result in an "unknown compilation problem".

Check your environment variables M2_HOME, JAVA_HOME and PATH to make sure the Maven and Java paths are consistent between them.

If the issue is still present, then try to run "mvn clean install -DskipTests -pl :nuxeo-annot-gwt -X" and share the output.
