Hi Mike,
I setup a clean development environment and root caused the issue, and it looks like some dependency information causes Leiningen to stack trace error.
To work around this, please use http to connect, and remove the following dependencies:
e.g.:
[stardog-clj "0.5" :exclusions [
[com.complexible.stardog.protocols.snarl/client]
[com.complexible.stardog.reasoning.snarl/client]
[com.complexible.stardog.search.snarl/client]
[com.complexible.stardog.search.http/client]
[com.complexible.stardog.icv.snarl/client]]]
I'll push a 0.6 version of stardog-clj that removes these dependencies for now, and we'll release a 0.7 when they're fixed.
Thanks for reporting this.
Al
