Errors when trying to run a single spec in JRuby

I asked this on the IRC room, but nobody was in there at the time, so
I’ll
try again here.

I am interested in running some RubySpecs and hopefully provide patches
to
fix, but the docs aren’t helping me much. So, I asked on the chat room
and
got some help (thanks, btw):
http://logs.jruby.org/jruby/2011-11-30.html#T21-34-08

So I took a freshly cloned jruby.git repo and built it, then tried to
run a
specific spec:

So what does the 'Errno::ENOENT: No such file or directory - cannot
execute’error mean?

This is very peculiar…I’m going to try to get a Windows VM up and
running and see if I can reproduce it.

Does the machine you’re running on have any peculiar filesystem
permissions? Are you running as an administrator? I’m not sure how
Windows handles permissions anymore, but that would be my first
thought…something’s odd about the filesystem permissions or your
rights to it.

I had a similar problem when running the overarching specs on Windows XP
and it seems that the clone brings old binaries or some such things
(wasn’t
really clear). asariah helped me and ‘ant clean jar’ cleared things up
so
that the specs ran. Hope this helps.

I can create a jar just fine, but I seem not to be able to run any
single
spec without getting that error. I was thinking that maybe the syntax
was
goofy (differences between Windows and Mac users running one test) or
that
I needed to generate some other scaffolding somewhere else.

Hmmm, sorry. I think ‘ant clean’ was the important part. You will have
to
rebuild after running that command though.
