"To verify which sites are enabled, open Window > Preferences > Install/Update > Available Software Sites. To add sites, Click the Add... button, then right-click the link(s) below, copy the link(s), and paste them into Eclipse one by one as needed."

If you follow this path, then you never seen the screen to check the box for "All JBoss Tools" therefore you do not actually receive/download JBoss Tools.
