Class BapSshTransferCache

  • public class BapSshTransferCache
extends Object
    This class allows to handle the tracking of the files transferred to the remote servers so that those upload can be skipped if possible. The files are tracked via a per-job json cache file ("remoteResourceCache.json") which contains a map of the absolute paths of the uploaded files and the values: * Last access timestamp * MD5 Hash value The files are signaled to be uploaded in two scenarios: * They were not uploaded previously, they are now tracked and uploaded * They were already uploaded before, only if the file has newer access timestamp and a *different* MD5 value they are uploaded This is done for performance reasons, large files may take a long time to compute the MD5 hash so if they are not newer then there is no need to compute it because we already know that the upload will be rejected.
