pom.xml文件有问题，必须是"pom"，但是是"jar"，尚未更改包装

Question

我在很多地方搜索过，但似乎都没有工作。在我的pom文件的第一行，我得到

项目构建错误：父 POM 的打包无效，必须是"pom"，而是"jar"。

我首先尝试从其他工作pom文件中复制/粘贴第一行的类似代码，但没有运气。然后我尝试进入概述 ->工件 ->将包装从"罐子"更改为"pom"，但没有运气。我还尝试安装新软件，https://download.eclipse.org/m2e-wtp/releases/1.4/，但它无法连接。我尝试将依赖项上的 maven-shade-插件版本从 3.0.0 更改为匹配我的 maven 版本，即 3.3.9，但它无法连接。尽管 maven 在正确的道路上并且安装在那里并为其他 maven 项目工作，但我被告知我的环境可能有问题，所以我也尝试在其他地方运行它，如 IntelliJ，但遇到了其他问题。我正在使用Spring Tool Suites，这是eclipse的扩展。你们中有人知道如何解决这个问题吗？谢谢

Answer 1

错误指出您的<parent>是一个没有<packaging>pom</packaging>的项目。

因此，您要么使用了错误的项目作为父项目，要么您的父 POM 意外<packaging>jar</packaging>。

为了更详细地了解这一点，我们需要您的POM文件以及您父母的文件。
