Java Maven说，尽管存在依赖，但现在仍然存在依赖

我有一个包含两个模块的项目，我需要在另一个模块中使用第一个模块中的类。为此，我向第一个的pom文件添加了依赖项：

<dependency>
      <groupId>com.mdnaRabbit.worker</groupId>
      <artifactId>Worker</artifactId>
      <version>1.0-SNAPSHOT</version>
  </dependency>

尝试执行打包时，我有以下跟踪：

[ERROR] COMPILATION ERROR :

导入字符串没有用红色下划线

已解决：我需要运行“mvn安装”

也许这会有所帮助

<plugin>
    <groupId>com.mdnaRabbit.worker</groupId>
    <artifactId>WORKER</artifactId>
    <version>1.0-SNAPSHOT</version>
    <configuration>
          <!-- parameters and values common to all goals, as required -->
    </configuration>
</plugin>

com.mdnaRabbit.worker
工人
1.0-快照

或者尝试手动安装。

您是否在所依赖的项目上运行了“mvn安装”？您是在构建父模块还是子模块？您是否在辅助模块上执行过mvn安装？哦，NilsH，谢谢。我经常忘记运行“mvn安装”。你需要告诉我，你是maven的新手。你完全正确。我对编程一无所知。
