【问题描述】：

我是 Dagger 的新手。这是我的pom.xml：

应用程序在 Intellij 中运行良好。但是，在执行maven clean install 时，我收到以下错误：

官方文档不要求我们添加任何其他依赖项。我究竟做错了什么？这是一个多模块项目，有一个父级。

【参考方案1】：

添加这个：

  <repositories>
    <repository>
      <id>google-maven</id>
      <name>Google Maven Repo</name>
      <url>https://maven.google.com</url>
    </repository>
  </repositories>
