java - Maven 无法构建 pom

Question

我从spring初始化器下载了一个spring项目，并通过maven将其导入到sts中。

不幸的是，构建一直失败，并出现以下错误:

Project build error: Non-resolvable parent POM for com.dellteam:firstmicroservice:0.0.1-SNAPSHOT: Could not transfer
artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.0.RELEASE from/to spring-milestones (https:// repo.spring.io/milestone): Connection reset and 'parent.relativePath' points at no local POM

请参阅下面的pom.xml:

我以为我的 ISP 不允许我访问 https://repo.spring.io/milestone/ 但事实并非如此。 我完全可以访问这个网址。

我现在尝试清理和构建几次并删除.m2文件夹并再次尝试重建项目，但结果是相同的。

任何帮助将不胜感激。

Answer 1

这是您的互联网连接问题。检查是否需要配置代理服务器。您可以在.m2目录下的settings.xml中设置代理，检查This link用于配置代理。
