Aldo,
That is a resource only in CA's artifactory server, so you will not be able to satisfy that dependency as it exists in the POM. I have not checked this specific name formatter, but most of the time, you can work around any dependencies from that component by instead referencing the agent.jar you have downloaded instead.
The basic steps would be to remove this dependency and see what the build issues are to verify that the Agent.jar is satisfactory and then you'd have to update the POM to use a local .jar as a resource.
