## Interface VersionConstraint

- All Known Subinterfaces:
    MutableVersionConstraint

      @Incubating
      public interface VersionConstraint

  Represents a constrained version. By default, when a dependency has a version number, it is assumed that the version can be upgraded during conflict resolution (typically, version 1.15 can be upgraded to 1.16). However in some cases we don't want this behavior. This class represents the base spec of module constraints.
  Since:
    4.4
