Publish source jars on JitPack

[andilem]

Currently, no source JARs are published on jitpack, see e.g. https://jitpack.io/com/github/mapsforge/vtm/vtm/0.27.0/ or https://jitpack.io/com/github/mapsforge/vtm/vtm-android/0.27.0/.
This makes using the API very hard because there is no javadoc or annotations.
Please consider publishing source JARs together with the normal JARs.

If you know how to do this, please let us know.

You have something like this in your build.gradle files:

publishing {
    publications {
        maven(MavenPublication) {
            from components.java
        }
    }
}

Replace it by something like this:

// define how to build the source JAR
task sourceJar(type: Jar) {
    from sourceSets.main.allJava
    //from sourceSets.main.resources   // probably not required for you - depends on whether you have source relevant stuff in your resources
    archiveClassifier = 'sources'
}

publishing {
    publications {
        maven(MavenPublication) {   // or mavenJar(...)
            from components.java
            artifact sourceJar   // <-- add sourceJar artifact to the publication
        }
    }
}

Publish sources and Javadoc jars is implemented via #1290.
