Exception: clojure.lang.Compiler$CompilerException: java.lang.Exception: EOF while reading (core.clj:78)
This one is common enough..there is a parentheses missing.
Exception in thread "main" java.lang.Exception: Invalid token: /input (core.clj:64)
I struggled with this until I figured out that the parser complains about the next string declaration, if the previous string is missing trailing doublequotes.
