There is no way to download the artifact archive of a failed job.

[mstekel]

The JobApi::downloadArtifactsFile method uses job name and not job id that obviously means the artifact archive for a successful run of that job name (job name is not unique).
Gitlab API actually provides a method for downloading the artifact archive of any job (by job id):

GET /projects/:id/jobs/:job_id/artifacts

but your java wrapper for that API method, Job::getArtifactsFile, returns an instance of ArtifactsFile with only the file name and size - there is no way to access the input stream of the archive.

Please either add a method like public InputStream getBytes() to the ArtifactsFile class or provide an overloaded JobApi::downloadArtifactsFile that uses job id (and calls the Gitlab API I mentioned above).

I just added two methods to JobApi for downloading using the endpoint you referenced:
GET /projects/:id/jobs/:job_id/artifacts

They are:

// Download the artifacts archive by job ID and save to the specified directory
public File downloadArtifactsFile(Object projectIdOrPath, Integer jobId, File directory)

// Get an InputStream to download the artifacts archive for the specified job ID
public InputStream downloadArtifactsFile(Object projectIdOrPath, Integer jobId)

This is available in release 4.8.44, though it might take up to 24 hours for this to be available in the central repos.

Thank you.

If you could verify and close I would appreciate it.

Not in the repositories yet but I verified it locally. Thanks.
