Did you compare the opensearch-ml zip size before and after this removal? We can remove it for now but we probably will add some of them back to use Guava cache for better cache management if the zip size doesn't change much.

Hi @Zhangxunmt this PR is not really have the zip size optimization as it's main focus, but rather it was more meant about making the build file clean from exclusion and shading acrobatics and avoiding dependencies that can collide with opensearch runtime.

Now if we intend on keeping Guava going forward for various other reasons (e.g. Cache) then should we use runtime dependency instead of compile time? You can pass the guava to testImplementation instead and avoid the exclusions and shading?

PS: If that approach would work better then I'm open to iterate on it to move it there.

Some new PR merged to main branch. Rebase to make the CI pass?

@samuel-oci Can you rebase this PR and merge? It's been a long time. Not sure if it has new conflicts with recent commits. Currently still no plan to use guava for cache.
