Error on lein appengine-prepare

[canassa]

When I run lein appengine-prepare it output this error:

I am using lein 2.0 and appengine-magic 0.5.1-SNAPSHOT

[intronic]

I had a similar problem. Does anyone have lein 2.0.0, appengine-magic 1.5.1-SNAPSHOT, and appengine SDK 1.7.4 working? (I fixed the above error, but still could not get lein appengine-prepare and lein appengine-update to work.)

[wiseman]

I'm having this issue as well. Is appengine-magic a practical way to go for doing clojure on AppEngine, currently? Are there alternatives?

[gcv]

Heroku?

Seriously, appengine-magic v0.5.0 does work. It does not support the latest Clojure, Leiningen, or the App Engine SDK, but it does work. Otherwise, patches welcome — Leiningen 2 support is the highest priority. I'll take care of it when I have time.

[cninja]

I got around this by adding [lancet "1.0.2"] to the :plugins section of the project.clj file.
