Could not find io.flutter:flutter_embedding_debug

2021-12-23 14:31:19 浏览数 (1)

flutter SDK 及Android Studio插件的安装都是参照flutter的介绍和环境搭建（超详细）来进行的，flutter doctor一切正常。但新建flutter project后，运行就卡住了。

备注：

Dart version 2.8.2

Android Studio (version 3.6)

Flutter version 1.17.1

代码语言：javascript复制
Running Gradle task 'assembleDebug'...    
This is taking an unexpectedly long time.

运行时会卡在Running Gradle task ‘assembleDebug’…, 因为Gradle的Maven仓库在国外, 可以使用阿里的镜像地址。

具体报错如下，环境什么的 都OK

第一种解决办法：

在flutterSDK文件目录打开这个文件 flutter/packages/flutter_tools/gradle/resolve_dependencies.gradle添加

代码语言：javascript复制
repositories {
    google()
    jcenter()
    maven {
        url "https://storage.googleapis.com/download.flutter.io"
    }
	maven {
            url 'http://download.flutter.io'
    }
}

添加库

代码语言：javascript复制
maven {
    url 'http://download.flutter.io'
}

第二种就是在本地项目：

代码语言：javascript复制
        //应用下面maven远程仓库
        //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'
        }

或者采用第三种下面的方法：Flutter Maven repository should support HTTPS

flutterpackagesflutter_toolsgradle 目录下面的文件夹 flutter.gradle文件 MAVEN_REPO修改maven远程仓库修改

代码语言：javascript复制
    //private static final String MAVEN_REPO      = "https://storage.googleapis.com/download.flutter.io";
    private static final String MAVEN_REPO      = "http://download.flutter.io";//修改之后

不管是第一种方案还是第三种方案 都解决了我的问题，感谢指正。
