SpringBoot脚手架创建的boot项目打包出来的jar里没有BOOT-INF文件夹

1. pom.xml问题：脚手架生成出来的项目的pom.xml里没有 parent 标签而是出现了dependencyManagement标签
2. 直接打包可以打出来jar文件但是没有走boot的插件，而且jar包里没有BOOT-INF文件夹且无法启动

我尝试修改以后就可以了：
1. 注释掉dependencyManagement标签，然后把parent标签加回来
2. 把boot插件的多余配置删掉

org.springframework.boot
spring-boot-maven-plugin
${spring-boot.version}

Start by inspecting the generated project's pom.xml and compare its dependencyManagement, parent, and spring-boot-maven-plugin entries with a working Spring Boot project. Package the generated project and verify that the resulting JAR contains BOOT-INF and can start successfully.
