hatası vardı

Aşağıdaki kodu ekleyince;
configurations.all { resolutionStrategy.eachDependency { DependencyResolveDetails details -> def requested = details.requested if (requested.group == 'com.android.support') { if (!requested.name.startsWith("multidex")) { details.useVersion '25.3.0' } } } }

ilk belirttiğim hata yerine bu hata geliyor;
