Spring Boot Starter Web项目错误

Question

我打算开始一个春季启动项目。

我从spring工具套件创建项目。 之后，我运行“ MVN全新安装”，但我明白了。

我怎么解决这个问题？

看来您无法获取所需的依赖项。 与org.jboss.shrinkwrap有关。

无法在项目中心执行目标：无法解析项目com.gh.app:hub:jar:0.1的依赖项：无法在org.springframework.boot：spring-boot-starter-web：jar：2.0.0上收集依赖项.RELEASE-> org.hibernate.validator：hibernate-validator：jar：6.0.7.Final：无法读取org.hibernate.validator：hibernate-validator：jar：6.0.7的工件描述符.Final：无法传输工件org.jboss.shrinkwrap：shrinkwrap-bom：pom：1.2.3 from / to repo2（ https://repo2.maven.org/maven2 ）：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security。 provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径-> [帮助1] [错误]

我将验证您用来构建的Maven实例没有覆盖您应该用于Springboot的存储库位置。

另外，请尝试清除〜/ .m2 / repository文件夹，然后再次运行全新安装。
