A new Gradle plugin for creating Debian compatible packages (.deb) is available at Bintray. It allows you to package any files through a convenient Gradle build script configuration into a Debian package compatible file. You may also include your MavenPublications (.jar or .war) by only referring to their publication names. To use the plugin you need some knowledge about the package structure and configuration scripts. The Debian New Maintainers’ Guide, chapters 4 and 5, will help a lot.
