Example 63 with HttpRequest

use of co.cask.common.http.HttpRequest in project cdap by caskdata.

the class ArtifactClient method add.

/**
   * Add an artifact.

   * @param namespace the namespace to add the artifact to
   * @param artifactName the name of the artifact to add
   * @param artifactContents an input supplier for the contents of the artifact
   * @param artifactVersion the version of the artifact to add. If null, the version will be derived from the
   *                        manifest of the artifact
   * @param parentArtifacts the set of artifacts this artifact extends
   * @param additionalPlugins the set of plugins contained in the artifact that cannot be determined
   *                          through jar inspection. This set should include any classes that are plugins but could
   *                          not be annotated as such. For example, 3rd party classes like jdbc drivers fall into
   *                          this category.
   * @throws ArtifactAlreadyExistsException if the artifact already exists
   * @throws BadRequestException if the request is invalid. For example, if the artifact name or version is invalid
   * @throws ArtifactRangeNotFoundException if the parent artifacts do not exist
   * @throws IOException if a network error occurred
   * @throws UnauthenticatedException if the request is not authorized successfully in the gateway server
