  <p>I installed some local jars into local repository. </p>
  
  <p>When I want to update the jar in my project, I re-install the jar into the repository and then run lein deps. I am finding that somehow, the jar is not updated in my project. Even when I rm -rf everything in the libs folder, the new jar is not picked up. The only way I have been able to get this to work is to change the name of the jar. </p>
  
  <p>Its sort of odd because this occurs even when I have deleted all traces of the old jar (as far as I know) -- does lein hide a snapshot/cache of libs? </p>
