[lampajr]

JIRA:

https://issues.redhat.com/browse/BXMSPROD-1892

referenced Pull Requests:

• https://github.com/kiegroup/kogito-pipelines/pull/743

Added GitHub workflow to automate pull request backporting:

• create backporting pull requests whenever a pull request (having one or more labels backport-<branch>) is successfully merged.

How to replicate CI configuration locally?

Build Chain tool does "simple" maven build(s), the builds are just Maven commands, but because the repositories relates and depends on each other and any change in API or class method could affect several of those repositories there is a need to use build-chain tool to handle cross repository builds and be sure that we always use latest version of the code for each repository.

build-chain tool is a build tool which can be used on command line locally or in Github Actions workflow(s), in case you need to change multiple repositories and send multiple dependent pull requests related with a change you can easily reproduce the same build by executing it on Github hosted environment or locally in your development environment. See local execution details to get more information about it.
