我对 Spring 不太擅长，所以这里有什么问题？

【问题讨论】：

我们必须猜测错误是什么？你的 IDe 有错误吗？项目不建吗？
我应该在 IDE (Eclipse) 的哪个面板中查看？该项目无法构建。
从哪里构建命令行？蚀？您是否将其正确导入为 maven 项目而不是常规项目？
我将它作为 Maven 项目导入。我从 git bash 命令行构建它。
它失败了？我们仍然不知道错误或输出，请将其添加到您的问题中。

标签： spring maven pom.xml

【解决方案1】：

错误消息是“ReasonPhrase：HTTPS 必需”。这意味着您必须将 repo URL 从 HTTP 更改为 HTTPS。根据您的日志，现在是“http://repo.maven.apache.org/maven2”，必须更改为“https://repo.maven.apache.org/maven2”。

Source

编辑：日志显示您使用的是 Maven 3.1.1。 Maven 3.6.3 的超级 POM 已经包含 Maven Central repo 的 HTTPS URL，因此更新 Maven 应该会有所帮助。

【讨论】：

我搜索了 http://repo.maven.apache.org/maven2 的提及，但我什至在 maven 的 pom.xml 或 settings.xml 中都没有找到它。那么我在哪里可以更改呢？
您是否尝试将其添加到 settings.xml 中？它应该覆盖默认值。
重新安装 maven 可能会有所帮助。最新的maven版本（3.6.3）的super POM已经包含了HTTPS URL。
我使用的是 Maven 3.6.3；并在菜单 Window -> Preferences -> Maven -> User Settings 我将用户设置设置为 3.6.3 版本的 settings.xml ，为什么我仍然会收到错误？
我也在 pom.xml 中添加了这个：<repositories> <repository> <id>central maven repo</id> <name>central maven repo https</name> <url>https://repo.maven.apache.org/maven2</url> </repository> </repositories> 但仍然得到同样的错误！
