  We consider Einstein gravity in general dimensions, coupled to a scalar field
either minimally or non-minimally, together with a generic scalar potential. By
making appropriate choices of the scalar potential, we obtain large classes of
new scalar hairy black holes that are asymptotic to anti-de Sitter spacetimes
in planar coordinates. For some classes of solutions, we can promote the scalar
charge to be dependent on the advanced or retarded times in the
Eddington-Finkelstein coordinates, and obtain exact dynamic solutions. In
particular, one class of the collapse solutions describe the evolution from the
AdS vacua to some stable black hole states, driven by a conformally-massless
scalar. It is an explicit demonstration of nonlinear instability of the AdS
vacuum that is stable at the linear level.
