flutter问题，Could not find method maven() for arguments 的错误

Question

先贴配置，build.gradle

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

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

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

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

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

运行flutter run之后，报错如下

Please review your Gradle project setup in the android/ folder.

请问有人遇到过吗？查好久没找到答案。希望有大神帮忙解决下，谢谢谢谢

这个原因，应该是墙的原因。因为墙在，所以下载不了相关文件，建议换成阿里源。

我看你也换过阿里源，代码里有注释，估计可能失败过。我猜阿里源失败的原因应该是你配置过代理。

如果配置过代理，即使改成阿里源也是会报错的。所以你要先去掉代理。

我之前配置环境的时候也碰到了这个问题，所以记成了上述链接里的文章，希望对你有用。

解决了吗？我在集成barcode_scan 的时候遇到了同样的问题

请问楼主问题解决了吗，遇到了相同的问题
虽然改成阿里原也还是不行
