Since a few weeks (and probably gradle versions), I am unable to upload the archives to Maven Central. If I don’t invoke gradle with --stacktrace I get
$ gradle uploadArchives
> Task :smack-android:uploadArchives FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':smack-android:uploadArchives'.
> Could not publish configuration 'archives'
> Could not write to file '/home/flo/data/code/smack/smack-android/build/poms/pom-default.xml'.
using --stacktrace yields
Caused by: org.gradle.api.InvalidUserDataException: The configuration to scope mapping is not unique. The following configurations have the same priority: [org.gradle.api.artifacts.maven.Conf2ScopeMapping@856ed98c, org.gradle.api.artifacts.maven.Conf2ScopeMapping@62c4ce18]

I am using Gradle 4.4.1 to upload the archives of the FOSS library Smack.
I am not sure what the cause of this is, as I don’t remember changing anything related to POM configuration in Smack recently. Any help or pointers in the right direction to solve this is appreciated.
