How to publish library aar file on the basis of current build variant selected in android using maven

Question

I have three build variants - staging, debug and production in android library. I need to publish the aar file on maven but the constraint is that if currently selected build variant is debug or staging then only debugAar should publish and if release is selected then releaseAar should publish. By default gradle only publishes releaseAar.

Currently everytime I want debug variant I need to change "artifact(bundleReleaseAar)" to "artifact(bundleDebugAar)"
