Do the following steps:
执行以下步骤：
- Find your pom.xml in your files
- Right click on it --> Maven --> Import
- Wait for the project to load :D
- Press ctrl+alt+shift+s(This opens the Projects window.)
- Go to libraries and see if they are empty (they shouldnt)
- If they are post your full pom.xml please so I can see the problem
- If you still have a problem got to File --> Invalidate Caches /Restart
- Go to maven and Reimport All Maven Projects
- 在你的文件中找到你的 pom.xml
- 右键单击它 --> Maven --> 导入
- 等待项目加载：D
- 按ctrl+ alt+ shift+ s（这将打开“项目”窗口。）
- 去图书馆看看它们是否是空的（他们不应该）
- 如果他们发布了完整的 pom.xml，请让我看到问题
- 如果您仍然遇到问题，请转到文件 --> 使缓存无效/重新启动
- 转到 maven 并重新导入所有 Maven 项目
回答by Blekit
Option Maven -> Reimportshould force Intellij to reload all dependencies. Alternatively, as mentioned in comments you can click the Reimport All Maven Projectsbutton in Maven Projectsview.
选项Maven -> Reimport应该强制 Intellij 重新加载所有依赖项。或者，如评论中所述，您可以单击视图中的Reimport All Maven Projects按钮Maven Projects。

Open the module dependencies (press F12 on the module), go to Modules -> Dependenciesand make sure maven imports are part of the of this.
打开模块依赖项（在模块上按 F12），转到Modules -> Dependencies并确保 maven 导入是其中的一部分。

Try to import the project from sources, if this answerdidn't help you.
如果此答案对您没有帮助，请尝试从源中导入项目。

The following worked for me.
以下对我有用。
- Deleted the maven dependency from my local repository
- mvn clean install downloaded the dependency again
- File --> Invalidate Caches/Restart
- I still saw the compilation error
- on my mac, I hit option + enter, intellij asked me to add the jar to classpath
- build -> make project
- 从我的本地存储库中删除了 maven 依赖项
- mvn clean install 再次下载了依赖项
- 文件 --> 使缓存无效/重新启动
- 我还是看到编译错误
- 在我的 Mac 上，我点击了 option + enter，intellij 要求我将 jar 添加到类路径
- 构建 -> 制作项目

I had faced the same problem, and the issue was small. I had changed the location of settings.xml file of maven and Intellij was picking up the default from C:\users\.m2\settings.xml
我也遇到过同样的问题，而且问题很小。我已经更改了 Maven 的 settings.xml 文件的位置，Intellij 从 C:\users\.m2\settings.xml 中选择了默认值
So point your maven settings.xml to the correct file as below: File--> Settings--> Build, Execution, Deployment--> Maven then on the right window, override "User settings file" to the settings.xml where you have in your local disk.
因此，将您的 Maven settings.xml 指向正确的文件，如下所示：文件--> 设置--> 构建、执行、部署--> Maven 然后在右侧窗口中，将“用户设置文件”覆盖到您所在的 settings.xml在您的本地磁盘中。
If you have installed maven in a non-default location then this file you can find in: \apache-maven-3.2.3\conf\settings.xml
如果您在非默认位置安装了 maven，那么您可以在以下位置找到此文件：\apache-maven-3.2.3\conf\settings.xml

In my case, I had my own apache-maven-3.5.2 folder and a misconfiguration created my problem. Maybe it's your case too:
就我而言，我有自己的 apache-maven-3.5.2 文件夹，配置错误导致了我的问题。也许这也是你的情况：
In rush, I set the local repository to C:/my/folder/apache-maven-3.5.2/settings.xml, but it must be a folder so Maven didn't allow me to download the dependencies. Then I changed the default (in the picture) and it worked.
匆忙中，我将本地存储库设置为 C:/my/folder/apache-maven-3.5.2/settings.xml，但它必须是一个文件夹，因此 Maven 不允许我下载依赖项。然后我更改了默认值（在图片中）并且它起作用了。
