You’re leaving a lot of value on the table if you don’t make use of Java libraries (even the standard ones). Many open source projects are thin layers over Java bindings, and it’s a huge free buffet lunch if you can do that yourself. But as long as you know the interop syntax you can pick that stuff up as and when you need to. Many people get by googling some JVM command line parameters when they hit a problem (running out of heap space, bringing in additional modules etc) and there are still plenty of people who work in pure Clojure and claim never to have to think about Java or the JVM, even the Maven bits.
