Wicket version 6.15 referring to older Jar

I have gotten all the latest jars installed for the Wicket 6.15. I can verify
this in the Maven Dependencies directory.

For some reason, I feel it is still pointing to an older version of Wicket.
I am getting strange errors with the add method from the MarkupContainer.

Using the quick-start example, in the HomePage class I am getting an error
with:

add(new Label("message", "If you see this message wicket is properly
configured and running"));

The error is:
The method add(Component[]) in the type MarkupContainer is not applicable
for the arguments (Label)

Not sure why it is using Component[] as a argument and not Component...
childs

as I am used to.

I am using Eclipse.
