I am working on SAML One Login Toolkit and got the latest master branch from GitHub here and using Eclipse Oxygen. It should manually resolve all maven dependencies but unfortunately it is not. I tried to delete .m2 repository multiple times but this did not help me. I also tried maven force update. I am getting the following error
