I followed the instructions here: https://wiki.opendaylight.org/view/GettingStarted:_Eclipse and was able to browse controller code in eclipse.
I then switched to a new workspace and imported existing maven projects corresponding to the l2switch git repo.
When I try to cross-ref in eclipse, I get this error: The resource is not on build path of a Java project
I notice that there is no buildpath under Project->Properties Also Project->Properties>Builders only list a Mavenbuilder and not Java (unlike the Controller projects)
Please let me know what is teh additional config required.
