You can follow the below steps to fix this problem.

1. Open a terminal and go to the spring project folder.
2. Then execute the below maven command to force update the local maven repository.

3. You can see that the above command will download several jars from the maven repository again and build the project until success. Open eclipse and import the spring project again then the error is fixed.
