Answer 1

This thread elsewhere on SO might help.
Jenkins looks for the mvn binary under $M2_HOME/bin/.
The ws/trunk in your logs suggests M2_HOME is pointing to $WORKSPACE:
(in directory "<http://localhost:8090/job/bbc/ws/trunk")
But usually $WORKSPACE is a file path, not a url.
All of which is to say, double check both your M2_HOME and WORKSPACE env variables.
The M2_HOME in particular is confusing since Jenkins lets you defined it at both instance and job level.
