Forum: JRuby fatal: unrecognized argument: --format=format:%h

Dear all,
I just tried the most recent jruby snapshot from
http://ci.jruby.org/snapshots/
This is what I see here on my Mac OS 10.6.4 machine:
$ jruby -v
jruby 1.6.0.dev (ruby 1.8.7 patchlevel 249) (2010-09-01 fatal: 
unrecognized argument: --format=format:%h) (Java HotSpot(TM) 64-Bit 
Server VM 1.6.0_20) [darwin-x86_64-java]

Do you also get this fatal ... string inside the version message?

Cheers,
-- Jan

The error should not affect the fitness of the snapshot, so don't worry 
about that.

To be more precise… That's where the git revision is supposed to go if 
you build the binary from the source, like so:

$ git log -1 --format=format:%h
b9f8624

My guess is that the git version in the snapshot environment is either 
too old or too new, and the argument is not recognized.

Yes, that's exactly it -- the version of git on our CI server is too
old. It actually turned out to be easier to change the command used to
generate the hash to `git log -1 --pretty=format:%h` which is
compatible with git 1.6 on the CI server as well as newer versions.
The next snapshot should properly capture the revision from which it
was built.

Yep, version string is looking fine again now.

Thanks,
