I have an ivy repository and findbugs 2.0.0, anlong with bcel, findbugs-ant, etc are there. I've found this https://blogs.oracle.com/ritzmann/entry/running_findbugs_with_ant_tasks, which walks through doing this with maven. However, it's for an older version. With 2.0.0 I don't see a coreplugins. I've got findbugs attempting to run with coreplugins set to an empty string. I think that I'm close but don't know where to go next.
I've attached the build target and macro I'm using.
