Not sure what changed, but every time I run

I'm getting this exception.

Did you by any chance upgrade your Leiningen install recently?

@MichaelBlume I deleted and reinstalled leiningen yesterday to see if something became corrupt. :(

[jtbeckha]

Looking the leiningen release notes (https://github.com/technomancy/leiningen/releases) it looks like they had a plugin related bug in the 2.6.0 release. I ran into the same problem on 2.6.0, resolved it by upgrading to 2.6.1

[ku1ik]

I confirm upgrading to 2.6.1 fixes the problem.
