Hi Christian, Friend (at least in this version) and clj-http depend on different versions of org.apache.httpcomponents/httpclient. If the version friend wants wins (friend first in dependencies), clj-http gets an earlier version than it wants and fails because the earlier version does not provide the same classes.
If you put [com.cemerick/friend "0.2.1" :exclusions [org.apache.httpcomponents/httpclient]] then you will always get the version of httpclient that clj-http specifies, regardless of the order you specify the dependencies in. I don't know if that might cause a runtime problem for friend, but I have used this setup without a problem so far.
