Leiningen provides a build management tool around common project tasks. It is easy to install via a simple shell script and has reasonable options to run, build, or launch a repl. The ability to configure environments and dependencies is also very helpful. Review collected by and hosted on G2.com.

So far, I haven't experienced any major downsides. It would be nice to specify a JDK version to lock to in order to prevent issues like the recent java perf regression related to static assets. Review collected by and hosted on G2.com.
