Class ResolutionException

  • All Implemented Interfaces:
    java.io.Serializable
    public class ResolutionException
extends java.lang.Exception
    Indicates failure to resolve a set of requirements.

    If a resolution failure is caused by a missing mandatory dependency a resolver may include any requirements it has considered in the resolution exception. Clients may access this set of dependencies via the getUnresolvedRequirements() method.

    Resolver implementations may extend this class to provide extra state information about the reason for the resolution failure.
