@cliu123 I think @dblock has a better proposal for how to address this, could you look at #1627

That's a good proposal to generate securityPluginVersion dynamically. Thanks for calling out! We can have a separate PR to adopt that mechanism. But this PR is to remove -SNAPSHOT from the opensearch.version in plugin descriptor in order to fix the incompatility between security plugin and OpenSearch.
