Boot repl does not work with Clojure 1.7.0-alpha4

[grammati]

Here is what happens:

This is related to cgrand/parsley#15 via trptcolin/reply#159

The workaround for now is to start the REPL server with Clojure 1.7 and the client separately with Clojure 1.6.

# start the server in a Clojure 1.7 environment
$ BOOT_CLOJURE_VERSION=1.7.0-alpha4 boot repl -s wait

# start the client in a Clojure 1.6 environment
$ boot repl -c

I just verified that the issue is fixed in master in parsley, so if you want you can also build that from source and install in your local Maven repo. That will also fix the problem in a way that doesn't require two separate boot invocations.

This issue appears to be fixed now. Please reopen if it's not really fixed.

This was fixed for me with boot 2.0.0-rc9 by manually installing parsley master as mentioned above, but since I upgraded to rc12 the other day I get the exact same error again.

I've tried it with rc10 and rc11 and they both work as above. Just rc12 seems to be broken.

Versions in case they're useful:

BOOT_VERSION=2.0.0-rc12
REPL-y 0.3.5, nREPL 0.2.7
Clojure 1.7.0-alpha5
