No problem, feel free to copy/modify them, add a wiki page at
http://java.debian.net if you wanna coordinate the work.

No, it's in the Debian policy ;-)

Are you in a hurry? I do prefer we take our time but make things the
best possible. From my experience, if you do an upload without packaging
required libraries, nobody will package them in the future. See the
'log4j should be built from sources' in the BTS (liblog4j1.2-java).

Yes it is. I already begun the work, but there are a lot of problems
with Maven I'll explain later.

ATM, we do not use Maven to build them and it should not be needed. Ant
is good enough.

I did not know about the offline mode. It's not acceptable for Debian to
relay on a network to build something.

but we have ant that can already do this.

Every DD (or even non-DD) interested in Java packaging is highly welcome

The battle for Maven in Debian
- ------------------------------

If we want Maven in Debian, we have some question to resolve before
doing that.


I have this email for days but never find the time to end it! So here it
comes and sorry if it's incomplete :(
