During building I am getting this error. I added scarlet-lifecycle-android, before that everything worked fine. More than one file was found with OS independent path 'META-INF/io.netty.versions.properties'

When using Scarlet, I had to apply this lines in my packaging options:

packagingOptions {
    pickFirst "META-INF/INDEX.LIST"
    pickFirst "META-INF/io.netty.versions.properties"
}

Maybe you won't need need the first line but hopefully the io.netty.versions.properties pick first specification will solve your problem
