When using the Custom Tool option, it is mandatory to provide a custom stylesheet to convert unit tests results to Junit format.

By following the documentation, we stored the xsl file in $JENKINS_HOME/userContent/cunit/cunit-to-junit.xsl

And we configured the plugin with a custom tool stylesheet pointing to $JENKINS_HOME/userContent/cunit/cunit-to-junit.xsl

This is not working when building on a slave machine, as the path $JENKINS_HOME/userContent/cunit/cunit-to-junit.xsl is not relevant on a slave (only for the master)

What about supporting URL instead, so using $JENKINS_URL/userContent/cunit/cunit-to-junit.xsl could work.
