Build Error when AAR does not contain classes.jar

Target Platforms Mobile

I am trying to include the latest Google Firebase files into my project. I have put the files under /Assets/Plugins/Android:

example:

/Assets/Plugins/Android/firebase-core-9.4.0.aar

When I try to build the android version of my project, I get the following error:

Moving Temp/StagingArea/android-libraries/firebase-core-9.4.0/classes.jar to Temp/StagingArea/android-libraries/firebase-core-9.4.0/libs/classes.jar: No such file or directory

I checked and firebase-core-9.4.0.aar does not have a classes.jar file. From my understandings AAR files are not required to have a classes.jar file inside them.

Is there a work around for this? As it stands, this error blocks me from building the android version of my project. I am using Unity 5.4.2f2

Hello,
classes.jar is a mandatory file for the aar plugin. Create an Android library  |  Android Studio  |  Android Developers
