Answer 1

Go to this folder:
'../.m2/repository/org/jvnet/staxex'
and for all of the versions, remove all the files inside the directories except from the .jar and .pom files.
If that does not help, try removing entire directories.
For me sometimes this helps also in order to force the checks bypassing local cached data:
mvn -U clean install
