That's correct. When --has-package-version is specified, the
debian.hasPackageVersion property is added to the pom installed in the
package. mh_installpom did that in maven-repo-helper, but not
maven-debian-helper before the version 2.2.

I checked mh_make, it handles this properly. The --has-package-version
flag is only added if the version of the package matches the version of

Intuitively I think the version constraints on the binary packages
should be picked from the version constraints of the source package (so
controlled by the maintainer). On the other hand, it's rather common to
forget versioning the build dependencies, and this --has-package-version
mechanism is often handy to prevent accidental migrations to testing of
packages that actually need another dependency still blocked for some
reason. This greatly improves the consistency of the migrations.
We probably need a lintian rule that checks if the version of the pom
matches the version of the package when --has-package-version is
specified (actually the pom version must be less than the package
version, this allows some divergences such as a package with the version
1.2.3+ds1 and the pom with the version 1.2.3). This will allow us to
easily identify and fix the packages affected.
