automatically increment bwc version

[kaituo]

Is your feature request related to a problem? Please describe

We need to bump the bwc version in every release (example: opensearch-project/anomaly-detection#775) because only the latest N-1.x will be upgradable to N.0 (e.g., from 2.x to 3.0) when that ships.

Known issue: opensearch-project/OpenSearch#5076
latest development: opensearch-project/OpenSearch#5091

Describe the solution you'd like

Could you automate bumping bwc version similar to release version (e.g., opensearch-project/anomaly-detection#774)?

Hi @kaituo,

You can do that by updating the updateVersion task in your build.gradle file. You can tell the task what all it needs to update https://github.com/opensearch-project/anomaly-detection/blob/main/build.gradle#L793-L802
For example, check this notification plugin repo's task https://github.com/opensearch-project/notifications/blob/main/notifications/build.gradle#L115-L130 it updates even the github workflows.

Let us know if this solves your problem. Thanks!

I think we could use opensearch_version from gradle properties for this one. Our current version bump workflow is incrementing this version everytime and this is pretty much the same as the version used for bwc. Only difference I'm thinking right now would be the -SNAPSHOT suffix.
I could elaborate this PR opensearch-project/anomaly-detection#778 to accommodate the changes.

Thanks @gaiksaya Thanks for the link.

@zelinh Thanks for doing it. As we are using latest 2.x for 3.x bwc testing, whenever we increment 2.x version we need to update the bwc version in 3.x.

A solution added by k-nn team https://github.com/opensearch-project/k-NN/blob/2.x/build.gradle#L327, that can increment the bwc version in the same existing gradle task updateVersion, sample PR for incrementing BWC version https://github.com/opensearch-project/k-NN/pull/826/files.
