# file opensearch-min-2.0.2-SNAPSHOT.x86_64.rpm
opensearch-min-2.0.2-SNAPSHOT.x86_64.rpm: RPM v3.0 bin opensearch-2.0.2~SNAPSHOT-1

There should not be any license here as core doesnt sign rpms to start with.
I wonder why gradle check is trying to check the license.

Thanks.

Update: resolved if you dont use AL2/CentOS but only use Ubuntu.
