有谁知道任何使用 Maven 构建到 RPM 的 Web 应用程序？ RPM Maven Plugin提供构建到 RPM 的功能，但缺少文档。

具体来说，我正在寻找一个包含多个模块的示例，即 Chapter 8. A Multi-module Project ，来自“Maven 实例”系列。

只有一个模块的例子是:

最佳答案

所以，事实证明我在提问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，我一直在寻找一个“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。

关于java - 使用 rpm-maven-plugin 的多模块 Web 应用程序示例？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7883891/
