问题：Android Studio中更新同步Gradle 失败

       

Gradle sync failed: Could not find com.android.tools.build:gradle:3.0.1.    Searched in the following locations:    https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom    https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.jar    Required by:    project :    Consult IDE log for more details (Help | Show Log) (2s 787ms)

解决办法： 在工程目录下的build.gradle文件中，添加 google() 这一行。

buildscript {    repositories {
            //添加        google()        jcenter()    }    dependencies {        classpath 'com.android.tools.build:gradle:3.1.1'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}allprojects {    repositories {
    　　　　 //添加        google()        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}
