【问题描述】：

我正在 Eclipse IDE 中为 Maven 上的 android 项目创建 POM 文件。我还在 settings.xml 文件中修改了我的代理设置。我在命令提示符下收到两个错误： 1)

Project build error: Unresolveable build extension: Plugin 
 com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.9.0-rc.3 or one of its dependencies 
 could not be resolved: The following artifacts could not be resolved:

和 2)

Project build error: Unknown packaging: apk

对于第二个错误，我尝试了Android with maven? Apkunknown上的提示，但无济于事。这是我的 pom 文件：

我非常感谢您的建议和 cmets。另外，我正在使用以下版本的 maven 和 java：

【参考方案1】：

运行命令

mvn eclipse:eclipse

确保 eclipse 可以看到这些库。这意味着进入 Eclipse 中的 projectsetup/buildpath/libraries 编辑器并添加变量 M2_REPO 以指向您的本地 maven 存储库（例如 /home/nacho3d/.m2/repository 之类的东西）

实际上，您的错误在我看来就像 maven 找不到 android-maven-plugin 的依赖项。

如果不行，则需要设置代理：Configuring a proxy

Setting.xml 文件位置

settings.xml 文件可能存在两个位置：

Maven 安装：$M2_HOME/conf/settings.xml

一个用户的安装：$user.home/.m2/settings.xml

【讨论】：

然后从这里配置代理maven.apache.org/guides/mini/guide-proxies.html

在哪里可以找到 settings.xml 文件？

$M2_HOME 的值是多少？

@SagorAhmed 那是 maven 主文件夹。在 Windows 中，它看起来像 C:\apache-maven-3.3.9\conf

如何找到用户名和密码？

【参考方案2】：

在你的 pom.xml 中添加这行代码并尝试重建你的项目。

这个插件管理可能会帮助你。

<pluginManagement>
  <plugins>
    <plugin>
      <groupId>com.jayway.maven.plugins.android.generation2</groupId>
      <artifactId>android-maven-plugin</artifactId>
      <version>3.9.0-rc.2</version>
      <extensions>true</extensions>
    </plugin>
  </plugins>
</pluginManagement>

您应该将此依赖项添加到您的项目中。

<dependency>
    <groupid>com.google.android</groupId>
    <artifactid>android</artifactId>
    <version>4.0.1.2</version>
    <scope>provided</scope>
</dependency>

然后使用命令

mvn eclipse:eclipse // to reset all .classpath files

和

mvn clean

不确定，但希望能解决您的问题。

【讨论】：

编辑后我的 xml 文件如下所示：paste.ofcode.org/r9AQZEKg8KnjgRE7GVsvD9。但同样的错误存在。
