@vanisrikanithi from the provided pipeline link, I noticed that you tested it only for the zip type. In the spec, you mentioned that the Jenkins unarchive step supports multiple formats like zip, tar, gz, etc.

Can you first confirm all the types supported by the Jenkins unarchive step? Then, test them with plugins/archive in Harness. If any type isn’t supported, we can consider adding it as an enhancement.

@Ompragash made few changes to the existed plugin Achive to support the tar and gz formats as well tested successfully in the Harness pipeline. Below are the pipelines for different formats.

zip, gz, tar.

Could you please review them and confirm the changes?

Thank you.
