This project originally showed a compile problem we had with cascalog. But now it looks like a leiningen / classloading Clojure issue. There is a combination of defrecord (in the "library" project), import and require (in user.clj) that leiningen doesn't like.
The problem can be worked around by adding an :aot in the library project. However, some say that this would be a bad style. Also it would be tiresome to have to go and sprinkle :aot everywhere.
Try this to cause a java.lang.ClassNotFoundException record-holder.def.ParallelAggregator (just a random class name borrowed from cascalog):
cd lib/record-holder
lein install
cd ../..
rm -rf target && lein do clean, deps, compile && lein repl
You can produce a similar without using leiningen, like this: ./install.sh && ./compile.sh && ./run.sh. Notice how that works when you enable aot in lib/record-holder/project.clj. Notice how it works when you remove (require '[record-holder.def]) from test/user.clj, too.
The clojure version is 1.6.0
The lein version is: Leiningen 2.3.4 on Java 1.7.0_51 OpenJDK 64-Bit Server VM
The error looks like this:
[class-not-found(master)]$ ./install.sh && ./compile.sh && ./run.sh

Or it may use like this, when using lein:
[class-not-found(master)]$ rm -rf target && lein do clean, deps, compile && lein repl
