Answer 1

This happens because you have the Maven default repository configuration that updates artifacts from the repositories once a day.

To solve this issue, you have 2 options:

1. Force maven to update using the -U option in the maven build command
2. Delete the directory of the dependency and run again the build command

Last but not least, you can change the updatePolicy of the repository. Give a look at the Maven Repositories doc
