*Problematic git configuration*
{code}
$ git config -l | grep format
format.pretty=%C(yellow)%h%Creset %s %C(red)(%an, %cr)%Creset
{code}
*Result of 'git show' with this format.pretty option*
This output is not parseable by the buildnumber plugin.
{code}
[DEBUG] consume line 4689188 Factory: remove unused funtions (tqueste, 2 days
ago)
{code}
*Workaround*
Remove the format.pretty configuration option. The plugin runs successfully.
*Solution*
Either the plugin disable the format.pretty option when running, or it stopped
with a warning ("'format.pretty' option used. Cannot continue").
