Flutter配置Gradle鏡像，解決國內(nèi)下載慢問題

未優(yōu)化之前

程序運行時會卡在Running Gradle task 'assembleDebug'...如下提示信息

Flutter assets will be downloaded from https://storage.flutter-io.cn. Make sure you trust this source!
Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...
Running Gradle task 'assembleDebug'...

此時Gradle正在下載gradle構(gòu)建工具以及相關(guān)依賴庫，由于官方gradle默認(rèn)配置的依賴下載服務(wù)器處于國外，國內(nèi)用戶訪問非常緩慢，常常一個依賴下載就要花半天時間，好在國內(nèi)有阿里、清華等鏡像源，我們可以配置鏡像代理加快依賴的下載

優(yōu)化步驟

修改build.gradle

進(jìn)入項目目錄的android/build.gradle，修改為如下，注意不要注釋掉google()和mavenCentral()，因為部分依賴可能鏡像源沒有，gradle找不到的話會報錯

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/spring/'}
        maven { url 'https://maven.aliyun.com/repository/google/'}
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin/'}
        maven { url 'https://maven.aliyun.com/repository/spring-plugin/'}
        maven { url 'https://maven.aliyun.com/repository/grails-core/'}
        maven { url 'https://maven.aliyun.com/repository/apache-snapshots/'}
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/spring/'}
        maven { url 'https://maven.aliyun.com/repository/google/'}
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin/'}
        maven { url 'https://maven.aliyun.com/repository/spring-plugin/'}
        maven { url 'https://maven.aliyun.com/repository/grails-core/'}
        maven { url 'https://maven.aliyun.com/repository/apache-snapshots/'}
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

修改gradle-wrapper.properties

進(jìn)入android/wrapper/gradle-wrapper.properties文件

distributionUrl的值用鏡像源替代，需要注意的是后面的gradle版本需要和替換鏡像源前的gradle版本一致文章來源地址http://www.zghlxwxcb.cn/news/detail-752350.html

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-7.5-all.zip
