I have a bunch of duplicate class errors, how do I solve this? I tried a lot of solutions online and I couldn't
like this in my build.gradle:

dependencies {
    configurations.all {
        exclude group: 'com.google.zxing'
    }
}

and I couldn't solve it, how do I fix when two cordova plugins is exporting same class ?
