Flutter 卡在 Running Gradle task ‘assembleDebug‘... 的解决方法

1 flutter项目的android目录中，项目的build.gradle

        maven {
    
     url 'https://maven.aliyun.com/repository/google' }
        maven {
    
     url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
    
     url 'https://maven.aliyun.com/nexus/content/groups/public'}
        google()
        mavenCentral()

2.flutter的sdk中进行设置，处于此目录下C:\fluttersdk\packages\flutter_tools\gradle\flutter.gradle

...
buildscript {
    
    
    repositories {
    
    

        maven {
    
     url 'https://maven.aliyun.com/repository/google' }
        maven {
    
     url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
    
     url 'https://maven.aliyun.com/nexus/content/groups/public' }
    }
    dependencies {
    
    
        classpath 'com.android.tools.build:gradle:3.4.0'
    }
}
...

3 flutter的sdk中进行设置，处于此目录下

C:\fluttersdk\packages\flutter_tools\gradle\resolve_dependencies.gradle,

...
repositories {
    
    

      maven {
    
     url 'https://maven.aliyun.com/repository/google' }
      maven {
    
     url 'https://maven.aliyun.com/repository/jcenter' }
      maven {
    
     url 'https://maven.aliyun.com/nexus/content/groups/public' }
      maven {
    
    
           url "https://storage.flutter-io.cn/download.flutter.io"
       }


}
