Paul Cager commented on MNG-3356:
---------------------------------
This error will only affect the *Debian* Maven package, and happens because
Debian are using commons-cli version 1.1 (rather than version 1.0 which
standard Maven uses).
Please see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=458895
and
http://issues.apache.org/jira/browse/CLI-137
for a full description of why this is happening. A revised Debian package is
being prepared.
In summary:
version 1.1 of commons-cli introduced a more rigid interpretation of the API
specification for the hasArg() method of OptionBuilder, such that hasArg()
implies there can only be *one* instance of the argument (I think there is a
remaining bug in the commons.cli package which I'll take up with them). This
means that the second "-D" option is taken to be an argument, rather than an
option. In version 1.0 of commons-cli this restriction was never enforced.
Maven should really be calling the hasArgs() method to indicate there can be
unlimited "-D" arguments. I've attached the patch Debian is using for this
problem.

> Reporter: Christian Koelle
> Priority: Critical

> After upgrading to 2.0.8 on Debian the handling of multiple (more than one)
> -Dkey=value cli options fail, i.e. something like:
> mvn plugin:goal -Dkey1=value1 -Dkey2=value2
> fails with:
> Invalid task 'key2=value2': you must specify a valid lifecycle phase, or a
