Running Gradle task ‘assembleDebug‘

Posted 2023-04-07 fangli11223344

原本项目可以正常跑起来，在安卓真机上正常运行的，后来不知道怎么滴，突然就跑不起来了，但是在ios设备上可以正常运行，后续判断主要是版本不匹配导致的，以及无法访问google服务。

话不多说，先来看看问题的呈现

具体问题呈现如下：

Running Gradle task 'assembleDebug'...

Retrying Gradle Build: #2, wait time: 200ms
[!] Gradle threw an error while downloading artifacts from the network.

主要解决方案如下：

若是因网络原因无法访问google服务，可以使用国内镜像代替，主要修改之处为：

1. android文件夹下build.gradle文件修改

将下面两行代码进行注释

google()
mavenCentral()

新增阿里云镜像如下

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' 

2. 修改gradle版本，android/gradle/wrapper/gradle-wrapper.properties，具体版本可查看

https://services.gradle.org/distributions/

distributionUrl=https\\://services.gradle.org/distributions/gradle-7.2-all.zip

项目运行成功的话，~/.gradle/wrapper/dist/gradle-7.2-all/路径下应是如此

若该路径下一直是下方这样的话，则表示gradle相应的版本未下载成功

此时，你可以自己去https://services.gradle.org/distributions/这里找到你要下载的版本手动下载下来，直接用.zip替换上面的两个就好了

此处另外需要关注两件事情，其一是java版本与gradle版本匹配

其二是gradle版本与gradle插件版本匹配兼容

android/build.gradle中classpath 'com.android.tools.build:gradle:4.1.0' 指的就是gradle插件版本，andriod/gradle/wrapper/gradle-wrapper.properties中就是gradle插件所需的gradle版本

3. flutter sdk路径下，如/Users/fl-10026268/fvm/versions/3.0.5/packages/flutter_tools/gradle/flutter.gradle文件修改

buildscript 
    repositories 
        // 注释
        // google()
        // mavenCentral()
        //  新增镜像
        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 
        /* When bumping, also update ndkVersion above. */
        classpath 'com.android.tools.build:gradle:4.1.0'
    

/// https://storage.flutter-io.cn 替换 https://storage.googleapis.com
private static final String DEFAULT_MAVEN_HOST = "https://storage.flutter-io.cn";  ///  "https://storage.googleapis.com";

4. flutter sdk路径下，如/Users/fl-10026268/fvm/versions/3.0.5/packages/flutter_tools/gradle/resolve_dependencies.gradle文件修改

// http://download.flutter.io 替换 $storageUrl/download.flutter.io
repositories 
    google()
    mavenCentral()
    maven 
        url "http://download.flutter.io"
        // url "$storageUrl/download.flutter.io"
    

5. flutter sdk路径下，如/Users/fl-10026268/fvm/versions/3.0.5/packages/flutter_tools/lib/src/http_host_validator.dart修改

/// Common Flutter HTTP hosts.
const String kPubDevHttpHost = 'https://pub.flutter-io.cn/';  /// https://pub.dev/
const String kgCloudHttpHost = 'https://storage.flutter-io.cn/';  /// https://cloud.google.com/

/// MacOS specific required HTTP hosts.
const List<String> macOSRequiredHttpHosts = <String>[
  'https://cocoapods.org/',
];

/// Android specific required HTTP hosts.
List<String> androidRequiredHttpHosts(Platform platform) 
  return <String>[
    // If kEnvCloudUrl is set, it will be used as the maven host
    if (!platform.environment.containsKey(kEnvCloudUrl))
      'https://dl.google.com/dl/android/maven2/',
      // 'https://maven.aliyun.com/repository/google/',
  ];

通过以上几个步骤的修改，基本上就可以解决此问题了，因本人不是安卓开发，我在这个问题上耽误了好些天，终于解决让项目跑起来了，特在此总结一下经验，希望后来人不会因此耽误太多时间。

【问题讨论】：

你能告诉我错误吗

在运行了几次之后构建现在失败了...异常：Gradle 任务 assembleDebug 失败，退出代码为 1。这是消息

这没有帮助，将之前的其他行复制并粘贴到您的问题中

您是否尝试过文件>无效缓存重启

试过无效缓存/重启

【参考方案1】：

您是否尝试过使用flutter clean 进行干净构建？您能否发布更多错误和代码？

【参考方案2】：

尝试清空缓存“C:\Users\dell.gradle\caches”并重新运行项目。您还应该在构建项目时检查事件日志错误。

【参考方案3】：

在您的 android studio 中，cd 到 android 目录，然后从终端运行： 毕业清洁 gradlew 构建 然后运行应用程序。 如果它不起作用，请尝试flutter clean。 同时删除用户目录中的 .gradle 文件夹。 这需要一些时间，但它会运行。
