flutter run 之后卡在 Running Gradle task 'assembleDebug'

遇到这个问题；就算开着代理也一直卡着，通过不了，

网上最常见得答案就是修改配置

项目目录/android/build.gradle 文件

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' }
    }
}

还需要修改flutter sdk里面得 flutter安装目录\packages\flutter_tools\gradle\flutter.gradle文件里得

buildscript {
    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'
    }
}

我按照这些修改完之后还是有问题。最后又看了其他答案，就是先把gradle下载在本地；然后把指向改到本地

先查看项目依赖得gradle版本

项目目录\android\gradle\wrapper\gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

然后就按照distributionUrl这个地址 去下载gradle到本地(如果下载不了可以开启代理)

然后把配置distributionUrl改成 指向本地得gradle

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=file\:/D\:/gradle/gradle-5.6.2-all.zip
