Question 1: Scanning errors (1): 1 Could not read pom.xml
When importing the Maven project into eclipse, the above error occurs, because the pom.xml file has content that cannot be parsed. The solution:
Delete the content in pom.xml, then import it, wait until the import is successful, and then copy the original content.
