Leiningen:

$ lein --version
Leiningen 2.5.3 on Java 1.8.0_45-internal OpenJDK 64-Bit Server VM

And clojure in project dependencies is version "1.7.0"

Ok looking at those source lines and re-reading my project.clj it turned out to be user error: the content in my :builds section was just [...] instead of the required [{...}] . Perhaps more thorough validation for clearer error messages would be a good idea.

@seprich Yeah, it looks like leiningen.garden/validate_builds has a call to clojure.core/name that's a little too assumptive. A patch is most certainly welcome.
