项目生成错误：不可解析的父POM：无法传输org.springframework.boot：spring-boot-starter-parent：

Question

有人帮我解决我在尝试保存pom.xml文件时遇到以下问题：

项目生成错误：不可解析的父POM：无法将org.springframework.boot:spring-boot-starter-parent:pom:2.5.0从http://UK.maven.org/maven2缓存在本地存储库中，在UK的更新间隔已过或强制更新之前，将不会重新尝试解析。原始错误：无法将项目org.springframework.boot:spring-boot-starter-parent:POM:2.5.0从/到UK(http://UK.maven.org/maven2):null到http://UK.maven.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.5.0/spring-boot-starter-parent-2.5.0.POM，且“parent.relativePath”指向没有本地POM

这是我的pom.xml

被缓存在本地存储库中，看起来您的maven无法加载尝试重新安装maven，并尝试使用https://start.spring.io生成这个项目
