java - 项目构建错误 : Invalid packaging for parent POM [unknown-group-id]:[unknown-artifact-id]:[unknown-version], 必须是 "pom"但实际上是 "jar"

Question

当我为 spring-boot 创建启动项目时，我在 pom 文件中收到此错误。这只是为了创建一个基本的 Spring Boot 项目

Project build error: Invalid packaging for parent POM [unknown-group-id]:[unknown-artifact-id]:[unknown-version], must be "pom" but is "jar"

<!-- This is the pom which from https://docs.spring.io/spring-boot/docs/current/reference/html/getting-started-first-application.html -->

Answer 1

您的父项目有 <packaging>JAR</packaging>不是 POM。要创建具有所有所需依赖项的 Spring Boot 项目，您可以使用 https://start.spring.io/ .
