public interface Repository
Represents a collection of resources available to Ivy. Ivy uses one or more repositories as both a source of resources for Ivy enabled build systems and as a distribution center for resources generated by Ivy enabled build systems.

A repository supports the following fundamental operations

  • retrieving a resource from the repository.
  • transferring a resource to the repository.
  • retrieving a listing of resources.

Resource Retrieval

get(String, File) retrieves a resource specified by a provided identifier creating a new file.

Resource Publication

put(Artifact, File, String, boolean) transfers a file to the repository.

resource Listing

list(String) returns a listing of file like objects belonging to a specified parent directory.
