Why can't to add android to eclipse

[AC Question]

I am trying to add android to eclipse neon and keep getting the following errors. The Tracer for OpenGL ES was the first one I tried by itself. I have tried both all six development and one at a time to no avail.

Your original request has been modified.
"Tracer for OpenGL ES" will be ignored because it is already installed.
Cannot complete the install because of a conflicting dependency.
