Upload sources to nexus repository with gradle

Question

I successfully uploaded my jars to a nexus repository using the maven plugin for gradle but it didn't upload the sources. This is my configuration:

uploadArchives {
    repositories{
        mavenDeployer {
            repository(url: "http://...") {
                 authentication(userName: "user", password: "myPassword")
            }
        }
    }
}

I searched and found that I can add the sources by adding a new task.

task sourcesJar(type: Jar, dependsOn:classes) {
     classifier = 'sources'
     from sourceSets.main.allSource
}

artifacts {
     archives sourcesJar
}

This works fine but I think there must be a better solution by configuring the maven plugin, something like uploadSource = true like this:

uploadArchives {
    repositories{
        mavenDeployer {
            repository(url: "http://...") {
                 authentication(userName: "user", password: "myPassword")
            }
            uploadSources = true
        }
    }
}

There is no better solution than what you described yourself. The gradle maven plugin is uploading all artifacts generated in the current project. That's why you have to explicitly create a "sources" artifact.

The situation also doesn't change when using the new maven-publish plugin. Here, you also need to explicitly define additional artifacts:

task sourceJar(type: Jar) {
    from sourceSets.main.allJava
}

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

            artifact sourceJar {
                classifier "sources"
            }
        }
    }
}

The reason is that gradle is more about being a general build tool and not bound to pure Java projects.
