Cannot resolve external dependency com.android.tools.build:aapt2:4.0.1-6197926 because no repositori

在 gradle 里面加上这个

allprojects { repositories { google() jcenter() maven { url "http://maven.aliyun.com/nexus/content/repositories/releases" } maven{ url "https://oss.sonatype.org/content/groups/public" } } }
