While it is possible to build packages with all sources inside the repo, our policy is generally to have the source compressed and placed on the source server. Uploading to the source server can only be accomplished by a CBL-Mariner developer. Please request help in your PR for uploading your sources to the source server. To check the source server see [https://cblmarinerstorage.blob.core.windows.net/sources/core/< source tar >].

I have no access to rerun that CI check Check Package CGManifests / Check Package CGManifests but it seems like some internal Github issue, could i please ask someone to trigger it again?

Closing & Re-Opening PR to trigger stuck github checks

[mfrw]

I have triggered a test build:
PR-7407

A note about the the prior test builds, they do build the package, but fail on authselect as it is a rutime dependency.

Have we verified the working of this package post a build ?

[adobrzhansky]

Package was installed with no issues the only thing was to add extended repo from where authselect would come.

All the modules after installation exists in the lib dir reference

Plugin activation and proof of working reference

LGTM :)
