Gradle: 5.1.1 User Guide section "Publishing" uses deprecated "classifier" attribute

Created on 16 Jan 2019 · 3Comments · Source: gradle/gradle

The code sample in 5.1.1 User Guide section "Publishing", sub-section Adding custom artifacts to a publication, uses the deprecated Jar task attribute "classifier".

Expected Behavior

The code sample should use the currently recommended, non-deprecated way of adding custom artifacts to a publication.

Current Behavior

The code sample uses the deprecated Jar task attribute "classifier":

task sourcesJar(type: Jar) {
    classifier = 'sources'
    from sourceSets.main.allJava
}

task javadocJar(type: Jar) {
    classifier = 'javadoc'
    from javadoc.destinationDir
}

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java

            artifact sourcesJar
            artifact javadocJar
        }
    }
}

I've recently upgraded to 5.1.1 and started getting deprecation warnings regarding this issue.

This issue is, notably, the only reference I've been able to find to this deprecation and I cannot, for the life of me, find the _proper_ non-deprecated way to handle this.

I realize that it's outside of the scope of your issue, but do you think you could elaborate on the updated method? I'd appreciate it. <3

EDIT:

Embarrassingly, I discovered an alternative, non-deprecated method soon after posting this. I'm not sure if it's the recommended or intended way, but it works.

Rather than the typical classifier = "sources" that we've all grown used to, we're supposed to use the archiveClassifier which returns a Property<String>, meaning your method looks as follows.

classifier = "sources"

To:

archiveClassifier.set("sources")
