🚀 build.gradle which forces all subprojects to use a single version of support library

build.gradle

ext {
    supportlib_version = '28.0.0'
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex')) {
                details.useVersion "$supportlib_version"
            }
        }
    }
}
