flutter 的项目内配置

// android/build.gradle 内，将 repositories 中的 google 和 jcenter 替换成如下代码:

buildscript {

    ext.kotlin_version = '1.3.50'

    repositories {

        //google()

        //jcenter()

        maven { url 'https://maven.aliyun.com/repository/google' }

        maven { url 'https://maven.aliyun.com/repository/jcenter' }

        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

    }

    dependencies {

        classpath 'com.android.tools.build:gradle:3.5.0'

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }

}

allprojects {

    repositories {

        // google()

        // jcenter()

        maven { url 'https://maven.aliyun.com/repository/google' }

        maven { url 'https://maven.aliyun.com/repository/jcenter' }

        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

    }

}

rootProject.buildDir = '../build'

subprojects {

    project.buildDir = "${rootProject.buildDir}/${project.name}"

}

subprojects {

    project.evaluationDependsOn(':app')

}

task clean(type: Delete) {

    delete rootProject.buildDir

}

同时在 flutter sdk 中

// path/to/flutter/packages/flutter_tools/gradle/flutter.gradle 中，重复上述操作
