    mavenCentral()
    maven { url "https://repository.cloudera.com/artifactory/cloudera-repos/" }

}

jar {
    from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    manifest.attributes("Main-Class":"org.project.seismic.Process_XY")
}

Could you clarify a bit what you're asking? What is the directory structure you're looking at? What have you tried? — Hiery Nomus

Ok, first of all, the source on a SourceDirectorySet takes another SourceDirectorySet. The srcDirs method however takes paths. Change that block to the following:

sourceSets {
  main {
    java {
      srcDirs ['src/org', '../../../SharedClass/org']
    }
  }
}

And you can easily add a second jar task as follows:

task secondJar(type: Jar) {
  name = other-main-jar
  from ...
  manifest.attributes(...)
}

assemble.dependsOn(secondJar)

This will register a new Jar task called secondJar and makes sure that when the project is assembled, this jar is also created.
