我已将 mavenCentral（）添加到项目级别的build.gradle文件中。 Gradle同步成功。
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.1'
classpath 'com.google.gms:google-services:4.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
mavenCentral() }
}
task clean(type: Delete) {
delete rootProject.buildDir

我尝试将appcompat版本从28降级到15.但错误仍然相同。所以我再次将其更改为28并从build.gradle文件中删除了该maven url，因为我在某处读取了google（）是否存在因此我删除了那个。之后那些依赖错误会自动解决。最后gradle成功构建。感谢@giudigior和@AlexMamo回复......
