原因
The artifact_definition table, used to store the definition of all your artifacts, has several columns for storing artifact name, pattern, location and so forth. When column src_directory on that table is NULL the SCP Task fails and throws the above errors when trying to fetch the artifact definition data. The reason why that column is NULL not yet known. To confirm if that's the case on your instance you can run the below query (please make sure to replace the build key with your own one:
select *
from artifact_definition ad
join build b
on ad.producer_job_id = b.build_id
where b.full_key = 'PROJ-PLAN-JOB'
and ad.src_directory is null;ソリューション
- Access your Bamboo instance URL https://<your-bamboo-URL>/build/admin/edit/defaultBuildArtifact.action?buildKey=PROJ-PLAN-JOB page and re-save the artifact definition for the artifact the shared artifact that you are using on your SCP task.
- Run your affected plan and confirm that the error is gone.
