我正在尝试执行 maven-jaxb2-plugin-sample-episode-0.7.4（在此处解释并提供下载）以尝试单独的架构编译。尽管它编译了第一个模式 (A)，但它在第二个模式 (B) 中失败了，因为它无法解析工件 maven-jaxb2-plugin-sample-episode-a-maven:jar:0.7.4。

我mvn assembly:assembly从命令行（Windows）执行，这是我得到的错误：

  Try downloading the file manually from the project website.

  Then, install it using the command:
      mvn install:install-file -DgroupId=org.jvnet.jaxb2.maven2 -DartifactId=mav

  Alternatively, if you host your own repository you can deploy the file there:

该示例应该按原样工作，我做错了什么？在实际场景中，我有超过 10 个模式必须编译为不同的情节，所以我需要自动处理（即不需要为每个单独的工件执行“mvn something”）

该模块maven-jaxb2-plugin-ample-episode-b-maven依赖于maven-jaxb2-plugin-ample-episode-a-maven.

当mvn assembly:assembly从父文件夹（包含两个模块）运行时，它会为 jar 构建 jar maven-jaxb2-plugin-ample-episode-a-maven，但不会将其安装在本地存储库中。

然后，当它尝试构建maven-jaxb2-plugin-ample-episode-b-maven时，它会查找依赖项 ( maven-jaxb2-plugin-ample-episode-a-maven)，但无法在本地存储库中找到它。因此错误。

问题是，为什么要运行mvn assembly:assembly用于创建二进制发行版的？两个模块中都没有程序集描述符。

mvn install工作正常并成功构建两个模块。
