I think lein checkout will be useful for this as well - https://github.com/technomancy/leiningen/blob/master/doc/TUTORIAL.md#checkout-dependencies

Yep. Checkouts worked perfectly. Thanks guys!

yeah, sorry - that too if you are using lein projects hah

I use checkouts often to dev 2 projects in somewhat tandem

be careful though checkouts are local and shield you from real build issues later

when you use a checkout dep - it overrides whatever you declared about that dep in your project.clj - such as version number is ignored - you just get whatever is in your local directory via the symlink

the docs for checkouts already warn similarly though
