Null pointer exception using lein swank on version 2.0.0

[boechat107]

I removed all the old files from .lein/ and ran lein self-install, installing the version 2.0.0. To make a test, I used lein new test and tried to run lein swank inside the folder of the new project. The result was this:

java.lang.NullPointerException

My "profiles" file is the same used in the "profiles guide".

The problem was solved returning to the 2.0.0-preview10 version of leiningen.

[technomancy]

The profiles guide is just outdated here; if you use the latest version of lein-swank it works fine.

Yes, it really works! Thanks!
