Hi @nverno. I'm trying out this commit, but when I do M-x eclimd-start after opening a Java file in my project I get: Not currently in eclim project.

I'll look into it further to see if it's my setup.

[nverno]

Yea, I see the same issue. There also is an issue with eclimd-stop, which hangs on accept-process-output.

[nverno]

Hm, it breaks the buttercup tests though since the mockup isnt a real process. What to do...
It would be nice to have a better mock-up to write tests against.

Hi @nverno. I tried your latest commit and the start sentinel portion works for me now. However, stopping eclimd still hangs and the tests fail. Do you want me to look into that?

[nverno]

I think the stopping eclimd should add a check in eclimd--match-process-output, eg. line 255

(while (and (process-live-p eclimd-process) (not finished-p)
   ....)

but it breaks the previous buttercup tests that rely on the fake mock-up process. The called-interactive-p is hacky and the specs work when I run them locally (emacs 27.0.5), but I don't know if that is due to a change in the function or something else.

I've only just started looking into buttercup, so I'm not sure how to remedy the testing sitch.

I'll break it into two issues, this just deals with the eclim starting outstide project part
