Maven未能构建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，构建不断失败，出现以下错误：

项目生成错误：的不可解析父POMcom.dellteam:firstmicroservice:0.0.1-SNAPSHOT:无法传输
工件org.springframework.boot:spring-boot启动器父级：pom:2.1.0.RELEASE从/到春季里程碑(https://repo.spring.io/metri里程碑(：连接重置和"parent.relativePath"指向无本地POM

请参阅下面的pom.xml:

</project>

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。

我现在尝试了几次清理和构建，删除了.m2文件夹，并再次尝试重建项目，但结果是一样的。

如有任何帮助，我们将不胜感激。

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，请选中此链接以配置代理。

Answer 2

将Spring插件发布存储库添加到插件存储库。这样它就可以找到弹簧弹簧-马达-滑块-2.1.0释放。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>
