[closed] Osmosis unit tests fail (latest git version, Feb. 9, 2012)

I cloned todays current git repository, but the build stops somewhere because of a failed unit test. The build results in a jar file in the dist/ directory, but that doesn't run either.

Here is the last bit of output from running "ant all":

checkstyle: [cs:checkstyle] Running Checkstyle 5.4 on 75 files

build_test:

ne or more junit tests failed.

Here is the output when I try to run the osomosis application:

$ osmosis -h

I guess the question is: what's wrong?
