Bug#458895: maven2: commons-cli.jar is the culprit

[Mike Paul]

Package: maven2
Version: 2.0.8-3
Followup-For: Bug #458895

Comparing the Java commands run by Debian's /usr/bin/mvn script and the
one in Apache's release, it turns out that the problem occurs if
the -Dmaven.home= option is set to /usr/share/maven2, but not if it
refers to Apache's distribution.

However, if I rearrange the Java command line so that the -DgroupId and
-DartifactId commands come *before* the class name
(org.codehaus.classworlds.Launcher), then it works even with
-Dmaven.home=/usr/share/maven2.  When they're given after the class name,
they're passed through to the application rather than interpreted by the
JVM, so it looks like Apache's version is manually handling -D options
given to the application, setting properties as if they'd been given to
the JVM, and Debian's version is not.

I ran a diff between /usr/share/maven2 and the contents of Apache's Maven
distribution, and found that there are a bunch of jars in
/usr/share/maven2/lib that aren't in the Apache distribution's lib/
directory.  It turns out that /usr/share/maven2/lib/commons-cli.jar is
the one that makes the difference:  if I copy that jar into a
freshly-unpacked copy of Apache's Maven distribution, the problem
occurs there too.

I don't know much about the commons-cli library, but since it does
command-line parsing, it stands to reason that it could be what's doing
the special handling of -D options given to the application.  Apache's
Maven distribution includes commons-cli in its maven-2.0.8-uber.jar,
which I guess I'm overriding when I copy Debian's commons-cli.jar into
the lib/ directory.

So, it looks like Debian's commons-cli isn't handling -D options passed
to the application like Apache's does.
