How to compile namespace in remote REPL

Question

I have a problem compiling .clj files which reside in a project where I run the nREPL server process:

1. I've created a new project using lein new xxx.
2. In the project folder I started up an nREPL by lein repl.
3. In another terminal window I started a client lein repl :connect localhost:12345/repl.

4. I created a simple namespace file and saved it inside the project in the appropriate location:

   (ns remote.one)
   (def foo 42)
   

5. Now on the client terminal I called this function

   (compile 'remote.one) 
   

I've got the below exception:

CompilerException java.lang.ClassNotFoundException: remote.one, compiling:(C:\Users\xxx\AppData\Local\Temp\form-init2429492334116477513.clj:1:1)

Now I would have expected the compile call to be executed in the server not on the client. Can it be done at all?

Thanks

I just tried it and it worked for me. What happened the first time I tried it was that I missed a step: setting the current directory as the project's. I see that this step is also missing from your description, maybe that's the reason it doesn't work in your case.

1. Create a new project using lein new remote.
2. Change the current directory cd remote.
3. Start the nREPL server from the project folder with lein repl :headless (which I realize now is also different from your description).
4. Open a new console and start the nREPL client lein repl :connect localhost:port/repl in ~/..
5. Create the file for the ns in ~/remote/src/remote/one.clj.
6. From the client evaluate (compile 'remote.one).
