Clojure REPL not working if CLJX 0.5.0 & CLJS 2665 on classpath

[Karsten Schmidt]

Am not entirely sure if that is related to recent REPL changes in CLJS, but I can't open a Clojure REPL in my CLJX project anymore :( Removing all other deps and trying various recent CLJS releases, the issue only seems to start w/ CLJS 0.0-2665, 2657 still is working fine...

lein repl

This is a problem with cemerick/piggieback and it's been already addressed. This project is using version 0.1.3 of piggieback, updating it to version 0.1.5 will fix these issues, although I don't know what side effects it may have.

I was able to get it working temporarily in my system by running the following commands:

cd <your-workspace>
git clone https://github.com/lynaghk/cljx.git
cd cljx
vim project.clj # change the cljx version and update piggieback to 0.1.5
lein do pom, jar, install

Then you can go ahead and change the version on your local project.clj and it should pick up the changes.

I did this because I'm waiting on the repo owner to update the dependencies. As I'm just a newbie, I didn't want to submit a PR without knowing the full side effects.

Yes, you need to upgrade ClojureScript and piggieback in unison. cljx will update its own piggieback dependency on the next release.
