[chef-dev] Mixlib:ShellOut fails with empty status

[< >]

Hi there, I try to develop a fix for the maven lwrp
(https://github.com/opscode-cookbooks/maven) and have run acros this problem:

When ein run "kitchen test" in the master of the git repo I see:
2013-05-05T15:32:21+00:00] DEBUG: Mixlib::ShellOut::ShellCommandFailed:
maven[mysql-connector-java] (maven::test line 6) had an error:
Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but
received ''

The output from the shell command looks like there is actually no error and it
is in the middle of execution (actually downloading, since its maven..) when
somethingh goes wrong. If I run the command from outside chef is succeeds. Is
there a way  to get a better Error Description from Mixlib:ShellOut? Anybody
seen it failing with status '' ?
