修改Android Studio的build-gradle默认模板

此处以Mac OS 为例

打开Finder，在左侧找到“应用程序” -> Android Studio -> 显示包内容

具体路径：

/Applications/Android Studio.app/Contents/plugins/android/lib/templates/gradle-projects/NewAndroidProject/root/build.gradle.ftl

打开该文件，即可进行自定义修改，例如我在此模板中增加了国内阿里云镜像

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/' }

修改后内容如下 ：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    <#if generateKotlin>ext.kotlin_version = '${kotlinVersion}'</#if>
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter/' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        google()
        jcenter()
        <#if includeKotlinEapRepo!false>maven { url '${kotlinEapRepoUrl}' }</#if>
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:${gradlePluginVersion}'
        <#if generateKotlin>classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"</#if>

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        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/' }
        google()
        jcenter()
        <#if includeKotlinEapRepo!false>maven { url '${kotlinEapRepoUrl}' }</#if>
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
