gradle publish jars with different classifiers, dependency missing

Question

Gradle new maven-publish plugin:

For multiple jars with different classifiers, e.g.,

source sets

src/foo/java
src/bar/java

dependencies {
    fooCompile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25'
    barCompile sourceSets.foo.output
}

Jars to build:

productName-1.0-foo.jar
productName-1.0-bar.jar

bar.jar has compile dependency on foo jar.

Gradle:

publishing {
    publications {
        mavenJava(MavenPublication) {
            groupId 'com.example'
            artifactId 'productName'
            version '1.0'

            artifact fooJar {
                classifier 'foo'
            }

            artifact barJar {
                classifier 'bar'
            }
        }
    }

    publishing {
        repositories {
            maven {
                url "$buildDir/repo"
            }
        }
    }
}

The published repository:

build/repo/com/example/productName/1.0/productName-1.0-foo.jar
build/repo/com/example/productName/1.0/productName-1.0-bar.jar
build/repo/com/example/productName/1.0/productName-1.0.pom

Only one pom without any dependency.

Now separate these with different artifactId (s)

publishing {
    publications {
        foo(MavenPublication) {
            groupId 'com.example'
            artifactId 'productName-foo'
            version '1.0'

            artifact fooJar {

            }
        }

        bar(MavenPublication) {
            groupId 'com.example'
            artifactId 'productName-bar'
            version '1.0'

            artifact barJar {

            }
        }
    }

    publishing {
        repositories {
            maven {
                url "$buildDir/repo"
            }
        }
    }
}

Each jar gets its own POM:

build/repo/com/example/productName-foo/1.0/productName-foo-1.0.jar
build/repo/com/example/productName-foo/1.0/productName-foo-1.0.pom

build/repo/com/example/productName-bar/1.0/productName-bar-1.0.jar
build/repo/com/example/productName-bar/1.0/productName-bar-1.0.pom

Two issues:

the classifier (foo, bar) is not after version in jar name.
the generated POM.xml files for foo and bar do not have dependency.

Here is an alternative approach that works for me. Something similar might work for you:

task sourcesJar(type: Jar, dependsOn: classes) {
    classifier = 'sources'  
    from sourceSets.main.allSource
}
// If needed the javadoc task can be commented, comment javadoc from artifacts and publish as well.
task javadocJar(type: Jar, dependsOn: javadoc){
    classifier = 'javadoc'
    from javadoc.destinationDir
}

task testJar(type: Jar, dependsOn: testClasses) {
    from sourceSets.test.output
    appendix 'test'
}

artifacts{
    archives sourcesJar
    archives javadocJar
    archives testJar
}

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
            artifact sourcesJar
            artifact javadocJar
        }
        mavenTest(MavenPublication) {
            artifactId project.name + "-test"
            artifact testJar {
                appendix 'test'
            }
        }
    }
}

artifactory {
    publish {
        defaults {
            publications ('mavenJava', 'mavenTest')
        }
    }
}

gradle publish jars with different classifiers, dependency missing
