sorry, beginner mistakes

just add

    packagingOptions {
        exclude 'META-INF/*.kotlin_module'
    }

works for me

[qrezet]

Can anyone explain this error and why the

packagingOptions {
    exclude 'META-INF/*.kotlin_module'
}

should fix it? 😢

To clarify to future readers of this bug: The magic fixing block needs to be put in the gradle app config under the android section, it seems.
