You've got an end-tag dependenciesbut no start-tag dependencies
你有一个结束标签依赖，但没有开始标签依赖
(missing tag should be between properties-tag and firts dependency)
（缺少的标签应该在 properties-tag 和 firts 依赖之间）
回答by dambros
Besides the <dependencies>tag missing, you have a problem on the <project>tag as well. This should do it:
除了<dependencies>标签丢失之外，您的标签也有问题<project>。这应该这样做：

My problem was a internet problem while download the dependencies, so some files was breaking. I solved deleting the directory ".m2" and executing mvn clean install to re-install the dependencies.
我的问题是下载依赖项时的互联网问题，所以一些文件被破坏了。我解决了删除目录“.m2”并执行 mvn clean install 重新安装依赖项的问题。

Do Project->Clean, just clean up the project and the error is gone.
做Project->Clean，把项目清理一下，错误就没了。
回答by Sachin Mehta
This mostly happens when you changes versions of eclipse on a single system. Try clearing .m2 directory. It should resolve the issue.
这主要发生在您在单个系统上更改 eclipse 版本时。尝试清除 .m2 目录。它应该可以解决问题。
