前言
新建了一个Flutter工程后，Run APP 却一直卡在了Running Gradle task ‘assembleDebug’… 这里。百度查询原因是因为 Gradle 的 Maven 仓库在国外, 因此需要使用阿里云的镜像地址。
1、修改项目中android/build.gradle文件
将 buildscript.repositories 下面的
//google()
//mavenCentral()注释掉，改成maven {allowInsecureProtocol = trueurl 'https://maven.aliyun.com/repository/google'
}
maven {allowInsecureProtocol = trueurl 'https://maven.aliyun.com/repository/jcenter'
}
maven {allowInsecureProtocol = trueurl 'http://maven.aliyun.com/nexus/content/groups/public'
}allprojects.repositories 同上修改
使用"阿里云"仓库为下载源，可能会报错(gradle的仓库地址不安全警告的错误)，因为配置了除 maven 中央仓库之外的其他不安全的仓库(一些国内的镜像仓库，如"阿里云"镜像仓库也是不安全的)，如下所示:
A problem occurred configuring root project 'Packer'.
> Could not resolve all dependencies for configuration ':classpath'.
> Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven(http://maven.aliyun.com/nexus/content/groups/public/)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.0.2/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.
* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.
解决方法:只需要在App项目工程的 build.gradle 中，使用 allowInsecureProtocol 属性(允许gradle使用"不安全"的仓库并且不报警告信息)即可
allowInsecureProtocol = true2、修改 Flutter SDK 中packages\flutter_tools\gradle\flutter.gradle文件
将 buildscript.repositories 下面的
//google()
//mavenCentral()注释掉，改成maven {allowInsecureProtocol = trueurl 'https://maven.aliyun.com/repository/google'
}
maven {allowInsecureProtocol = trueurl 'https://maven.aliyun.com/repository/jcenter'
}
maven {allowInsecureProtocol = trueurl 'http://maven.aliyun.com/nexus/content/groups/public'
}将 DEFAULT_MAVEN_HOST 值修改成 "https://storage.flutter-io.cn";
private static final String DEFAULT_MAVEN_HOST = "https://storage.flutter-io.cn";
