java - How to publish source into local maven repository with Gradle?

Question

I am developing two related project. One of which is "helper" one and another is "main" one. I am constantly updating "main", but from time to time I am also updating "helper" one. After then I am running install goal in gradle's maven plugin and get jars in local maven repo. After that I do gradle update in "main" project and have updated jars linked.

There are two questions.

1) If staying with maven plugin, then how to publish source code into local maven repo too?

2) Can I do similar without maven plugin, staying only with Gradle?

Answer 1

It's easy to publish sources with the "maven-publish" plugin:

apply plugin: "maven-publish"

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

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

          artifact sourceJar {
            classifier "sources"
          }
        }
     }
}

Then go publish to local maven run: gradle publishToMavenLocal
