java - pom.xml 文件有问题，必须是 'pom' 但是 'jar'，尚未对包装进行任何更改

问题描述

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 的包装无效，必须是“pom”但是“jar”。

我首先尝试从其他工作 pom 文件中为第一行复制/粘贴类似的代码，但没有成功。然后我尝试进入概述 - >工件 - >将包装从“jar”更改为“pom”，但没有运气。我也尝试安装新软件，https://download.eclipse.org/m2e-wtp/releases/1.4/，但无法连接。我尝试将依赖项上的 maven-shade-plugin 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。即使 maven 处于正确的路径并且安装在那里并且可以为其他 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 IntelliJ 等其他地方运行它，但遇到了其他问题。我正在使用 Spring Tool Suites，它是 Eclipse 的扩展。你们中有人知道如何解决这个问题吗？谢谢

解决方案

该错误表明您<parent>的项目没有<packaging>pom</packaging>.

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

为了更详细地了解这一点，我们需要您的 POM 文件以及您的父级文件。
