Some people, when running
lein repl, encounter a failure with the following error message:
Exception in thread "main" java.lang.reflect.InvocationTargetException
This is due a problem with the way Leiningen deals with the classpath. This problem is due to be fixed soon (the version as of this writing is 1.6.2), but in the meantime, an easy workaround exists.
From a terminal:
cd ..to move out of the ClojureScript One directory if you are currently in it. We need to run Leiningen to fix this problem, and leiningen is broken when run from within the ClojureScript One directory.
lein install org.clojure/clojure "1.2.1"
That's it: you should be able to
cd back into the ClojureScript One directory and successfully run
The problem arises out of the fact that Leiningen itself requires version 1.2.1 of Clojure. But ClojureScript One requires version 1.3.0 of Clojure. The way that current versions of Leiningen work, the classpath is set up in such a way that when Leiningen runs, this version mismatch causes a problem unless version 1.2.1 of Clojure is available in the local Maven repository (your
~/.m2 directory). Running
lein install org.clojure/clojure "1.2.1" installs version 1.2.1 of Clojure into the local Maven repository, preventing the problem from occurring.
