有谁知道使用 Maven 构建 RPM 的 Web 应用程序吗？这RPM Maven 插件 http://mojo.codehaus.org/rpm-maven-plugin/提供构建 RPM 的功能，但缺乏文档。
具体来说，我正在寻找一个包含多个模块的示例，即第 8 章多模块项目 http://www.sonatype.com/books/mvnex-book/reference/multimodule.html，来自“Maven 示例”系列。
仅包含单个模块的示例如下：

感谢您的任何/所有帮助！
所以，事实证明，我在提出问题时给出的例子是完全错误的，这可能是我没有得到我正在寻找的完整答案的原因。我真正想要的是一个安装到服务器的 RPM，它依赖于 servlet 容器（即 Tomcat）并将包含的 Web 应用程序（webapps）安装到 Tomcat 的 webapps 目录。
因此，这是正确的答案：

需要注意的是，我正在寻找一个“多模块”项目，但实际上我的意思是将多个相关的 Web 应用程序打包到一个 RPM 中。因此，此 Maven 构建的正确配置会告诉 RPM 安装程序需要 Apache Tomcat，并将 Web 应用程序安装到 Tomcat 中的正确文件夹中。
