Exception when installing Cake

[nathell]

This is a fresh Ubuntu 10.10 installation, with Ruby 1.8.7 and OpenJDK 1.6.0_20 installed. I checked out the cake Git repo and symlinked bin/cake to $PATH.

I try 'cake deps':

 [cake] connection to jvm is taking a long time...
 [cake] you can use ^C to abort and use 'cake kill' or 'cake kill -9' to force the jvm to restart

(This is a second try. The first time it didn't have the JDK installed, only the JRE, so it first complained about jps not being found, then downloaded the Cake jar, and then barfed on not finding jar.)

Retrying does not help. What next?

[ninjudd]

Sounds like you have an old version of clojure-protobuf. Try upgrading to the latest version in your project.clj and then rm -rf lib

[nathell]

This doesn't help; after removing lib, .cake and ~/.m2, cake deps re-downloads clojure jar and then barfs with the same exception.

[nathell]

It turns out that this was actually caused by my tasks.clj, which referenced the ant namespace.
