fix missing dependency error that magically appeared today

I have no idea what's going on, but lein was failing on everything because I had no.disassemble as a plugin, and I was getting the error that `org.eclipse.equinox:app:jar:1.0.0` couldn't be found.  I couldn't even figure out the where the transitive dependency was coming from, because `lein deps :tree` and `mvn dependency:tree` were both erroring out.  

This may not be the right solution to this (which I assume is because someone pushed a bad pom somewhere), but it seems to work.  Your call on whether to merge it or go in search of something less ad hoc.
