I experience the same error. I was using a jar which included:

implementation files('libs/commons-io-2.6.jar')

And in my app I too had included:

implementation files('libs/commons-io-2.6.jar')

So all I had to do was to remove that line from my app and not include the commons-io-2.6.jar file in my libs folder.
