I have a build script that calls the above line for each engine version specified. So my CI uses the AutomationTool. It works perfectly. You may have to use the “WhitelistPlatforms” property for your modules to prevent compilation for iOS / MacOS because that will throw an error if you are not using a Mac
"%Engine%_%Version%\Engine\Build\BatchFiles\RunUAT.bat" BuildPlugin -Plugin="%Plugin_Dir%\%PluginName%.uplugin" -Package="%PackageDir%\%Version%" -Rocket
