Tried cake clean, also removing classes libs build. No effect. This is a project which uses clojure-protobuf. Here's what I do:

cake clean
cake deps
cake proto
cake swank

when I get the above, cake hangs and does not return to the shell.

I wanted to narrow it down, but frankly I have no idea how, as I don't understand the backtrace at all.

This is with current cake from git. Says it's 0.5.4.

Digging in: This seems to be caused by my tasks.clj (placed in the source directory for my project), in particular by the ns statement:

(ns fablo.tasks
(:use [clojure.contrib.duck-streams :only (read-lines)]
[clojure.contrib.java-utils :only (file)]
cake cake.core cake.ant
[cake.tasks.jar :only [build-uberjar uberjarfile]])
(:import [org.apache.tools.ant.taskdefs Mkdir Copy](java.io IOException)))

rm -rf ~/.m2/repository seems to have fixed the problem.

hmm. i am unable to reproduce this. if you look in src/cake/project.clj there is a (def classpath ...). this is the file used by both cake.core and bake.core. could have been an old JVM running that didn't get restarted.

[jwr]

It was definitely not a running JVM, I killed all processes many times as I was trying to figure out what was going on. No amount of cleaning within the project directory did the trick, either. Finally, removing the maven repo did it, once and for good.

Maven is scary.
