MavenArtifactSet

A Collection of MavenArtifacts to be included in a MavenPublication. Being a DomainObjectSet, a MavenArtifactSet provides convenient methods for querying, filtering, and applying actions to the set of MavenArtifacts.

plugins {
    id 'maven-publish'
}

def publication = publishing.publications.create("name", MavenPublication)
def artifacts = publication.artifacts

artifacts.matching({
    it.classifier == "classy"
}).all({
    it.extension = "ext"
})
