I have the following in my build.sbt file to use Java-based .deb package building and publish to an Artifactory repository:
enablePlugins(JavaAppPackaging, DebianPlugin, JDebPackaging, DebianDeployPlugin)
However, when I try to do debian:publish, I get the error:
Creating changes file: /foo/bar/target/bar_1.0.0-SNAPSHOT_all.changes
java.lang.RuntimeException: Cannot generate .changes file without a changelog

[error] (debian:genChanges) Cannot generate .changes file without a changelog

I tried to add
changelog in Debian := ""
to my build.sbt as documented in the sbt native packager documentation (well, the documentation didn't specify what type it was, but I thought sbt would tell me if I had the wrong type so that would be fine). But then I received:
/foo/bar/build.sbt:31: error: not found: value changelog
changelog in Debian := ""
^
[error] Type error in expression
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?
I searched for an example showing setting the changelog, but I could not find one.
DebianDeployPlugin doesn't seem to work with JDebPackaging, and I'm not enough of an sbt guru to figure out why.
But to just build the .deb file, it's enough to add:
debianChangelog in Debian := Some(file("debian/changelog"))
and create a file debian/changelog containing
project-name (x.y.z) UNRELEASED; urgency=low
* Initial no-op application.
