While I haven’t tried uploading the artifacts with a deployment to Sonatype (or even a local repo), here’s what I managed to come up with a few weeks ago when trying to tackle the same problem.
android.libraryVariants.all { variant ->
def name = variant.buildType.name
if (name.equals(com.android.builder.core.BuilderConstants.DEBUG)) {
return; // Skip debug builds.
}
def task = project.tasks.create "jar${name.capitalize()}", Jar
task.dependsOn variant.javaCompile
task.from variant.javaCompile.destinationDir
artifacts.add('archives', task);
}
Then run the following:
./gradlew jarRelease
