lein install doesn't install the module zip file in local maven repository

[k-viktor]

This can be reproduced with

lein new vertx my-project
cd my-project
lein vertx buildmod
lein install
ls ~/.m2/repository/my-project/my-project/0.1.0-SNAPSHOT/

Only jar is installed. I would expect the zip file to be installed as well, so I can then deploy modules from my local repository.
