Hey @martin-gaievski
This file you are changing is the template that we used.
Could you change on this manifest which would be used for build? Thanks. https://github.com/opensearch-project/opensearch-build/blob/main/manifests/2.12.0/opensearch-2.12.0.yml

[martin-gaievski]

thank you @zelinh I've moved changes to correct file, please check

[zelinh]

Checks failed because of incompatible gradle and jdk version.
Since we recently upgraded to JDK21/gradle 8.5, opensearch-project/OpenSearch#11003, you should also upgrade and test your plugin to see if it supports that.
Blocking this PR for now.
Thanks.
