This is due to the fact that some of the maven packages provided by the maven module, which is declared default, do not provide all the subpackages the coresponding non-module rpm package provides.

The maven-resolver package in the module provides:

maven-resolver-api
maven-resolver-connector-basic
maven-resolver-impl
maven-resolver-spi
maven-resolver-transport-file
maven-resolver-transport-http
maven-resolver-transport-wagon
maven-resolver-util

The maven-resolver non-module package in addition provides:

maven-resolver
maven-resolver-javadoc
maven-resolver-test-util
maven-resolver-transport-classpath

The maven-wagon package in the module provides:

maven-wagon-file
maven-wagon-http
maven-wagon-http-shared
maven-wagon-provider-api

The maven-wagon non-module package in addition provides:

maven-wagon
maven-wagon-ftp
maven-wagon-http-lightweight
maven-wagon-javadoc
maven-wagon-providers
maven-wagon-scm
maven-wagon-ssh
maven-wagon-ssh-common
maven-wagon-ssh-external

Since the module is declared default, the packages in the module override the package from the normal rpm, and the packages from the normal rpm are not available for installation (dnf says they are excluded).

For the packages that are not provided by the module, the normal rpm version is not overridden. However, they are not installable since they depends on the non-module version of packages built from the same srpm (as they should according to the guidelines).

A srpm built as part of a module declared default must provide all subpackages that the non-module srpm builds, or alternatively obsolete the subpackages it does not build (this choice is only acceptable if there are no other packages with dependencies or build dependencies on the subpackage). Otherwise the subpackages provided by the normal rpm that are not excluded by the module become uninstallable.


Version-Release number of selected component (if applicable):
