Gradle Publish Task & Proguard

Question

I would like to publish an obfuscated artifact on Github Sonatype. I don't know how to specify the publish task to use the obfuscated artifact. The Proguard task creates a separate jar, in outjar, and this should be published. Is there any way to specify the jar to be used?

Can you please help me?

task proguard(type:proguard.gradle.ProGuardTask, dependsOn:['clean','jar']) {
    configuration 'resources/install/proguard.txt'
    libraryjars files(configurations.runtimeClasspath.collect())
    // CHECK IN gradle.properties org.gradle.java.home.
    libraryjars "${System.env.JAVA_HOME}/jmods/"

    injars "$buildDir/libs/dbs.jar"
    outjars "$buildDir/app-libs/dbschema.jar"
}
