问题

在编译Flutter项目的时候出现问题：

• **Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
• Get more help at https://help.gradle.org
  BUILD FAILED in 4s
  Finished with error: Gradle task assembleDebug failed with exit code 1**

原因

网络问题
从上面黑体字标注的结果来看：无法获得从https://jcenter.bintray.com/io/flutter/flutter_embedding_debug/ 获得到io.flutter:flutter_embedding_debug:1.0.0
并且进入该页面也无效（魔法也无效访问）

解决

进入android/build.gradle：
在repositories添加新的源：（阿里云），并且ban掉Google和jcenter源

//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' }
maven { url "http://download.flutter.io" }

PS：也可以添加其他源如清华，中科大等

如图：

示例代码如下：

buildscript {
    ext.kotlin_version = '1.6.10'
    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' }
        maven { url "http://download.flutter.io" }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.kotlin:kotlin-android-extensions:$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' }
        maven { url "http://download.flutter.io" }
    }
}
