Could you help me? Unfortunately, I can't add screenshots.. There are screenshots: http://screencast.com/t/iNaWO9gy http://screencast.com/t/iBGTyMpgH

Project settings - Libraries - empty;

reimport didn't help;

Answer 1

Do the following steps:

1. Find your pom.xml in your files
2. Right click on it --> Maven --> Import
3. Wait for the project to load :D
4. Press ctrl + alt + shift + s (This opens the Projects window.)
5. Go to libraries and see if they are empty (they shouldnt)
6. If they are post your full pom.xml please so I can see the problem
7. If you still have a problem got to File --> Invalidate Caches /Restart
8. Go to maven and Reimport All Maven Projects

Answer 2

Option Maven -> Reimport should force Intellij to reload all dependencies. Alternatively, as mentioned in comments you can click the Reimport All Maven Projects button in Maven Projects view.

Answer 3

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:

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.

Answer 4

打开模块依赖项（按模块上的F12），转到Modules -> Dependencies ，并确保maven导入是其中的一部分。

Answer 5

如果此答案对您没有帮助，请尝试从源中导入项目。

Answer 6

The following worked for me.

1. Deleted the maven dependency from my local repository
2. mvn clean install downloaded the dependency again
3. File --> Invalidate Caches/Restart
4. I still saw the compilation error
5. on my mac, I hit option + enter, intellij asked me to add the jar to classpath
6. build -> make project

Answer 7

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

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.

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

Answer 8

右键单击pom.xml ，然后单击Add as Maven Project
