Troubleshoot Eclipse's Maven project cannot refer to the MAVEN library error--MAC

I. Description of the problem

When using eclipse as a Maven project, sometimes updating the project or running the pom file may cause eclipse to fail to introduce the MAVEN library, and then report many JSP or other errors.

When I was using eclipse in my Mac, I ran into this error and started looking for a lot of things that didn't work out until I knew it was because Maven saved a copy of the library files that were needed in the project in Classpath. We need to remove all of the individual MAVEN libraries.

Ii. Solutions

1, Java build Path--> Libraries

To delete a single, single maven file that is referenced

2, in the Maven->java EE integration Check out the Enable Java Configuration

Use the above operation to get the result as shown:
