java - Maven 构建 pom 失败

问题描述

我从spring初始化程序下载了一个spring项目，并通过maven将它导入到sts中。

不幸的是，构建不断失败，出现以下错误：

项目构建错误：com.dellteam:firstmicroservice:0.0.1-SNAPSHOT 的不可解析父 POM：无法
从/到传输工件 org.springframework.boot:spring-boot-starter-parent:pom:2.1.0.RELEASE spring-milestones (https://repo.spring.io/milestone)：连接重置和“parent.relativePath”点在没有本地 POM

请看下面的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。这个网址对我来说是完全可以访问的。

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。

解决方案

将 Spring Plugin Release Repo 添加到 Plugin-Repositories。这样它就可以找到spring-boot-maven-plugin-2.1.0.RELEASE。在标签下添加以下行，如下所示：

<project>
  <!------ others lines -->
    <pluginRepositories>
     <pluginRepository>
        <id>repository.spring.release</id>
        <name>Spring GA Repository</name>
        <url>https://repo.spring.io/plugins-release/</url>
    </pluginRepository>
   </pluginRepositories>
 </project>
