POM错误:找不到org.springframework.boot

Question

我一直在尝试设置一个Spring启动项目,但是收到错误.我研究并尝试了各种选择但到目前为止没有运气.任何帮助,将不胜感激.

项目构建错误:不可解析的父POM:未能在http://repo.maven.apache.org/ maven2中找到org.springframework.boot:spring-boot-starter-parent:pom:1.1.3.RELEASE 在本地存储库中,在中心的更新间隔过去或强制更新并且'parent.relativePath'指向没有本地POM之前,不会重新尝试解析

POM.XML(父标记中的错误)

Answer 1

可能存在一些间歇性的互联网问题或其他问题.我昨天遇到了同样的问题.更新项目(在STS或Eclipse上,右键单击项目和Maven - >更新项目 - >勾选除脱机之外的所有内容)一段时间后修复它.

Answer 2

我在 maven-build 过程中遇到了类似的异常。

如果您使用代理网络 -settings.xml在您的 maven 文件夹中更新

../apache-maven-3.2.3\conf/settings.xml

settings.xml 内容

<proxies>
    <proxy>
      <id>...</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>....</username>
      <password>....</password>
      <host>....</host>
      <port>....</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
   </proxies>

project(right click) -> Maven -> Update project -> tick everything (except OfflinI)

我解决了问题。
