public final class ArtifactDownload extends ArtifactTransfer
A download of an artifact from a remote repository. A repository connector processing this download has to use setException(ArtifactTransferException) and setSupportedContexts(Collection) (if applicable) to report the results of the transfer.

  • Constructor Details

    • ArtifactDownload

      public ArtifactDownload()
      Creates a new uninitialized download.

    • ArtifactDownload

      public ArtifactDownload(Artifact artifact, String context, File file, String checksumPolicy)
      Creates a new download with the specified properties.
      Parameters:
      artifact - The artifact to download, may be null.
      context - The context in which this download is performed, may be null.
      file - The local file to download the artifact to, may be null.
      checksumPolicy - The checksum policy, may be null.

  • Method Details

    • setArtifact

      public ArtifactDownload setArtifact(Artifact artifact)
      Description copied from class: ArtifactTransfer
      Sets the artifact to transfer.
      Overrides:
      setArtifact in class ArtifactTransfer
      Parameters:
      artifact - The artifact, may be null.
      Returns:
      This transfer for chaining, never null.

    • setFile

      public ArtifactDownload setFile(File file)
      Description copied from class: ArtifactTransfer
      Sets the local file the artifact is downloaded to or uploaded from.
      Overrides:
      setFile in class ArtifactTransfer
      Parameters:
      file - The local file, may be null.
      Returns:
      This transfer for chaining, never null.

    • isExistenceCheck

      public boolean isExistenceCheck()
      Indicates whether this transfer shall only verify the existence of the artifact in the remote repository rather than actually downloading the file. Just like with an actual transfer, a connector is expected to signal the non-existence of the artifact by associating an ArtifactNotFoundException with this download. Note: If an existence check is requested, ArtifactTransfer.getFile() may be null, i.e. the connector must not try to access the local file.
      Returns:
      true if only the artifact existence shall be verified, false to actually download the artifact.

    • setExistenceCheck

      public ArtifactDownload setExistenceCheck(boolean existenceCheck)
      Controls whether this transfer shall only verify the existence of the artifact in the remote repository rather than actually downloading the file.
      Parameters:
      existenceCheck - true if only the artifact existence shall be verified, false to actually download the artifact.
      Returns:
      This transfer for chaining, never null.

    • getChecksumPolicy

      public String getChecksumPolicy()
      Gets the checksum policy for this transfer.
      Returns:
      The checksum policy, never null.

    • setChecksumPolicy

      public ArtifactDownload setChecksumPolicy(String checksumPolicy)
      Sets the checksum policy for this transfer.
      Parameters:
      checksumPolicy - The checksum policy, may be null.
      Returns:
      This transfer for chaining, never null.

    • getRequestContext

      public String getRequestContext()
      Gets the context of this transfer.
      Returns:
      The context id, never null.

    • setRequestContext

      public ArtifactDownload setRequestContext(String context)
      Sets the context of this transfer.
      Parameters:
      context - The context id, may be null.
      Returns:
      This transfer for chaining, never null.

    • getSupportedContexts

      public Collection<String> getSupportedContexts()
      Gets the set of request contexts in which the artifact is generally available. Repository managers can indicate that an artifact is available in more than the requested context to avoid future remote trips for the same artifact in a different context.
      Returns:
      The set of requests context in which the artifact is available, never null.

    • setSupportedContexts

      public ArtifactDownload setSupportedContexts(Collection<String> contexts)
      Sets the set of request contexts in which the artifact is generally available. Repository managers can indicate that an artifact is available in more than the requested context to avoid future remote trips for the same artifact in a different context. The set of supported contexts defaults to the original request context if not overridden by the repository connector.
      Parameters:
      contexts - The set of requests context in which the artifact is available, may be null.
      Returns:
      This transfer for chaining, never null.

    • getRepositories

      public List<RemoteRepository> getRepositories()
      Gets the remote repositories that are being aggregated by the physically contacted remote repository (i.e. a repository manager).
      Returns:
      The remote repositories being aggregated, never null.

    • setRepositories

      public ArtifactDownload setRepositories(List<RemoteRepository> repositories)
      Sets the remote repositories that are being aggregated by the physically contacted remote repository (i.e. a repository manager).
      Parameters:
      repositories - The remote repositories being aggregated, may be null.
      Returns:
      This transfer for chaining, never null.

    • setException

      public ArtifactDownload setException(ArtifactTransferException exception)
      Description copied from class: ArtifactTransfer
      Sets the exception that occurred during the transfer.
      Overrides:
      setException in class ArtifactTransfer
      Parameters:
      exception - The exception, may be null to denote a successful transfer.
      Returns:
      This transfer for chaining, never null.
