Question

项目构建错误：

com.example的不可解析的父POM：demo：0.0.1-SNAPSHOT：无法传输org.springframework.boot：spring-boot-starter-parent：pom：1.5.2.RELEASE from {{3}如果缓存在本地存储库中，则在中心的更新间隔过去或强制更新之前，不会重新尝试解析。原始错误：无法传输工件org.springframework.boot：spring-boot-starter-parent：pom：1.5.2.RELEASE from / to central（https://repo.maven.apache.org/maven2）：connect timed out和'parent.relativePath'points在没有当地的POM

我该如何解决这个问题？

这是我的POM.XML文件：

尝试强制更新依赖项。您的.m2可能有问题。 mvn clean install -U
