lein repl zip file is empty exception

Question

I get the error messages when I enter lein repl in my project root folder. I have tried to delete the .lein directory in home folder and redownload lein but it doesn't work for me.

Edit: I'm running leiningen 2.1.2 on ubuntu 12.10 64bit machine.

Note: If I run lein repl outside my project root folder, it is fine.

Answer 1

I have once successfully made that problem go away when using lein2 by running

lein clean

My next guess would be to move your ~/.m2/repository out of the way and try again.
