Yes, after I checked the code out, I just ran "mvn" from the directory, and
put all the compiled jar files in the target directory into my class path.
I did this for neo4j-rdf, neo4j-rdf-sail & the core neo4j. For APOC, I used
the contents of the lib directory from the download. I never saw any of the
dependency jars get generated into the target directory after the maven
build, which is probably how I got myself into this mess in the first place.
This is only the second time I've ever had to use maven, so I would not be
surprised if I've just made some terribly naive oversight due to my lack of
experience using it.
