POM not created for custom MavenPublication

[nucatus]

When a custom MavenPublication is built, the artifactory plugin fails to build the POM file.

$ gradle clean :api:artifactoryPublish                                  
:api:artifactoryPublish FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':api:artifactoryPublish'.
\> File '/sbox/gradle-arty/spcx.root/api/build/publications/clientLib/pom-default.xml' does not exist, and need to be published from publication clientLib

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Here is a snippet of the configuration:

[...]

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
        clientLib(MavenPublication) {
            artifact clientJar
            pom.withXml {
                asNode().appendNode('description', 'A demonstration of Maven POM customization')
            }
        }
    }
}

artifactoryPublish {
    publications(publishing.publications.clientLib)
}

if I do publications(publishing.publications.mavenJava), the build is successfull.

I have created a project to demonstrate the issue here: https://github.com/nucatus/sourcesets-arty.git

Gradle: 3.0
Artifactory Plugin: 4.4.4

This works OKish with Gradle 2.14.1, BUT the problem here though is that it publishes the wrong jar. It is not publishing the clientJar, but the default Jar. As you can see in the screenshot, the jar is off, but the POM is OK.
