A standalone jar that starts nREPL server with lighttable.nrepl.handler/lighttable-ops as handler can not be executed.

[kohyama]

I have a project whose -main starts a nrepl server with '(clojure.tools.nrepl.server/start-server :handler (clojure.tools.nrepl.server/default-handler #'lighttable.nrepl.handler/lighttable-ops))`

When I run the project with lein run, it works.

But lein uberjar-ed standalone.jar can't be executed by java -jar and throws java.lang.ExceptionInInitializerError below.

I don't sure if it's a problem of lighttable.nrepl.handler.
Does anyone know what's wrong?

It seems to be caused by CLJ-1544.
http://dev.clojure.org/jira/browse/CLJ-1544
So what should I do in this case?

[rundis]

You could try building lein-light-nrepl from source yourself (pending a 0.2.0 release of the clojure plugin)

• Clone/fork https://github.com/LightTable/Clojure
• cd lein-light-nrepl
• lein with-profile production install ; with-profile to ensure clojure-complete doesn't get test scope !
• change your lein-light dependency to 0.2.0

[kohyama]

Great!
It works fine with self-built 0.2.0.
Thank you so much for your comment, rundis.
I use this self-built version until the 0.2.0 release and hope the release will go well.
