Re: Packaging issue on gradle's library dependency

Hi Roger,

Thank you for contributing to Debian!

I haven't dug too much about your package, but I think you are right
about Proguard missing the POM files. Currently "proguard" does not
generate maven-repo data which are POMs stored in
/usr/share/maven-repo. It will be great to submit a wishlist bug to
src:proguard, but if you want to get your package prepared soon you
can avoid using gradle-debian-helper (--buildsystem=gradle) by
directly invoking Gradle in your debian/rules. But you need to do some
extra work:

# 1. Invoking Gradle

See <http://anonscm.debian.org/cgit/pkg-java/bintray-client-java.git/tree/debian/rules?h=debian/0.8.1-1>.
The point is you need to add "--offline --gradle-user-home
.gradlehome" and after the invocation you need to remove .gradle and

# 2. Patch build scripts

Replace all repository closures with:

repositories {
  flatDir { dirs '/usr/share/java' }
  maven { url 'file:///usr/share/maven-repo' }

After that the build should be successful. If any problems about
missing dependencies occur then you also need to replace the
dependencies' artifactId to the corresponding filenames in
/usr/share/java, and make the dependencies forward-compatible. For
example: "foo:bar:1.0" => "foo:bar:[1.0, )", like intervals you
learned from high school maths.

This is how I solve the problems before gradle-debian-helper appears.
I am not familiar with gradle-debian-helper yet so maybe ebourg and
apo may have some ideas on improving it according to this problem.
