Missed from gradle upgrade:

Use require rather than assert to ensure validation always run.

It looks like the validation isn’t currently being executed, because pom.withXml {} runs during the configuration phase (before the POM file is written), placing it inside a doLast block causes it to be skipped.

One alternative is to remove pom.WithXml block and parse the generated POM file directly using XmlParser, as we did previously:

val pomXml: Node = XmlParser().parse(destination)
