1. Problem description
When we use IDEA to create a Java Web project of Spring Boot, there will be an error that the package cannot be imported. For example, we create a Spring Boot basic project from the Spring official website, and then open it in the local IDEA to find the error.
Open pom.xm file and error message will appear.
Then right click, find Maven - > reimport, and report the same error
The local Maven warehouse didn't download any packages either
Open Maven Projects in the right sidebar
After clicking install, Maven warehouse has some packages, but @ SpringBootApplication still reports errors as shown in Figure 1.
Open the log file. You will be prompted that the maven project cannot be imported. You need to open the log file to view the details. Then we will open the log file to see why.
Click Help - > show log in Explorer,
After opening, open the idea.log file.
Find the log of the corresponding time, and the contents are as follows:

2. Solutions
We can see from the error information that these packages cannot be imported. I checked some materials and said that they were caused by incompatible versions. I used maven 3.6.3.
So I uninstalled maven 3.6.3 and downloaded it again maven3.6.1 , the pro test is effective, and I will not explain in detail the reinstallation of maven. After the installation is completed, reopen the project, and you will find it in the auto guide package, as shown in the following figure.
After the completion of the packet guidance, it can be found that the error message disappears.
