+```diff
++configurations.all {
++    resolutionStrategy {
++        eachDependency { DependencyResolveDetails details ->
++            if (details.requested.name == 'android-jsc') {
++                details.useTarget group: details.requested.group, name: 'android-jsc-intl', version: 'r224109'
++            }
++        }
++    }
++}
