I'm glad to hear that. And idea sharing goes both ways - your work on
Gradle helper gave me some ideas how Gradle integration in XMvn could
be improved and motivated me to finish it.

I think that XMvn should be extended to be able to produce and consume
native Debian repository format (basically standard Maven repo
format).  This way packages built with XMvn and maven-debian-helper
could be mixed freely.  No migration plan would be needed - package
maintainers could use either tool according to their preference.

What looks more difficult from my PoV is proper integration with dpkg
and debhelper/CDBS. Of course XMvn could be used directly from
standard rules file, but the goal is to avoid manual work and
boilerplate code whenever possible.

I hope that sharing code will be possible in some future too -- I will
try working on this as time allows.  My initial plan is to enhance
XMvn to be able to read/write Debian-like repo under
/usr/share/maven-repo, then package it for Debian, implement required
dpkg-specific code and create some PoC integration with debhelper 9.
