I have deleted multiple versions of castor dependencies in .m2 folder and updated maven. Cleaned the project and still the error wont go away, below is the maven dependency tree

I can see the getresolver method in castoe.xml jar file When I look at the stack trace - where getResolver is called - it is pointing to castor.XML's method.
