Can the maven-shade-plugin create a shaded pom for a module with packaging type pom?

I have a multi module maven project with a seperate xyz-distribution module that contains multiple assemblies. This module depends on all artifacts that go into the assemblies.

In my parent pom I have disabled deployment per default as I want only my distribution assemblies deployed.

Since there will be no individual artifacts in my production repository (only the distribution assemblies), the deployed distribution pom should also not list any dependencies. I tried to achieve this goal by including the maven-shade-plugin in my configuration.

But calling 'mvn install' always yields the following error

[INFO] Replacing original artifact with shaded artifact.
[INFO] Replacing null with C:\...\xyz-distribution\target\xyz-distribution-1.0-shaded.pom
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error creating shaded jar: null

Any ideas how to solve my problem?

parent pom (simplified):
