we have multiple jars like drop1, drop2.... dropN. At the end of testing is there any way to consolidate all these N drops into one single jar? without re writting a product rule to have all the rules of these drops?
I recommend coming up with a CICD solution to automate merging your branches, running test automation, and migrating your rulesets. Deployment Manager is available for this. You can also create your own with an Orchistration system like Jenkins.
