终于从Gradle 坑中爬出来了。Running gradle task 长时间被卡问题解决代码

为了见到这个Demo界面，害得我删了装，装了删，也最终下决心将系统从Win7 换到了Win10.

Baidu了不下100次。终于功夫不负有心人，模拟器终于跑出来了；

环境情况；

操作系统:Win10 X64

Android studio 4.1.2

Flutter : 1.27.0-4.0.pre

Git

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/google' }
        //google()
　　　　　//jcenter这个函数不知是不是重点，最终靠他解决了问题.就是加上花括号，写上url "http://jcenter.bintray.com/"
        jcenter(){
            url "http://jcenter.bintray.com/"
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/google' }


        //google()
        //jcenter()
    }
}

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

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

 其实问题就是不能下载gradle ，但试了N种方法，就是老卡在Running gradle task.

于是就换版本，改build.gradle文件的配置 ；
