Gem version configuration w/o launcher

How/where are the gem configurations stored?

I have built a Gem, and assigned it a version number.

Specifically, I’m trying to set up an automated build system for my project, which in-part needs to handle incrementing and building each version of the gem. Currently, changing the version number in gem.json, and then attempting to rebuild, will result in a crash at startup: https://forums.awsgametech.com/t/gem-version/752/1

I need to be able to modify that version number in an automated way, so my auto-builder can build a lumberyard project after changing the version number of my gem.

Help?

{LumberyardInstallLocation}\dev\SamplesProject\gems.json

Modify and re-write the json file with the new version number.
