Question

我在Spring Boot中部署应用程序时遇到了一些问题。我有以下应用程序结构。总共有三个项目第一个项目是项目Parent，它的包类型是war 第二个项目是简单的天气，它的包装类型是pom（我将来会添加一些maven模块）第三个项目是simple-webapp，它的包类型是pom（我将来会添加更多的maven模块）

简单天气和简单webapp都添加为父pom中的依赖

这是代码

父项目pom.xml

所以问题是当我尝试将父pom部署到tomcat时，它会显示以下消息

[ERROR]项目ProjectParent：projectparent：0.0.1-SNAPSHOT   （E：\ Dashboard \ workspace \ projectparent \ pom.xml）有1个错误[错误]
  价值'战争'的'包装'无效。聚合器项目需要   'pom'作为包装。 @第6行，第14栏

有什么建议吗？

Answer 1

您的父pom的<packaging>必须为pom，如错误消息中所述。你的simple-webapp pom的<packaging>应该是战争。你只需要切换它们。

此值必须为父包的pom。您的父包有两个模块：simple-weather模块包含您的应用程序simple-webapp模块将此应用程序包装为可部署的war文件。

在聚合pom中有问题
