flutter run 之後卡在 Running Gradle task 'assembleDebug'

flutter run 之後卡在 Running Gradle task 'assembleDebug'

遇到這個問題；就算開着代理也一直卡着，通過不了，

網上最常見得答案就是修改配置

項目目錄/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' }
    }
}

還需要修改flutter sdk裏面得 flutter安裝目錄\packages\flutter_tools\gradle\flutter.gradle文件裏得

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'
    }
}

我按照這些修改完之後還是有問題。最後又看了其他答案，就是先把gradle下載在本地；然後把指向改到本地

先查看項目依賴得gradle版本

項目目錄\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

然後就按照distributionUrl這個地址 去下載gradle到本地(如果下載不了可以開啓代理)

然後把配置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
