  In recent years, there have been controversy concerning the anomaly mediated
gaugino mass in the superspace formalism of supergravity. In this paper, we
reexamine the gaugino mass term in this formalism by paying particular
attention to symmetry which controls gaugino masses in supergravity. We first
discuss super-Diffeomorphism invariance of path-integral measures of charged
superfields. As we will show, the super-Diffeomorphism invariant measure is not
invariant under a super-Weyl transformation, which is the origin of the anomaly
mediated gaugino mass. We show how the anomaly mediated gaugino mass is
expressed as a local operator in a Wilsonian effective action in a
super-Diffeomorphism covariant way. We also obtain a gaugino mass term
independent of the gauge choice of the fictitious super-Weyl symmetry in the
super-Weyl compensator formalism, which reproduces the widely accepted result.
Besides, we discuss how to reconcile the gaugino mass term in the local
Wilsonian effective action and the gaugino mass term appearing in a non-local
1PI quantum effective action.
