Follow this design document.
https://github.com/swift-server/swift-aws-lambda-runtime/blob/sebsto/new-plugins/Plugins/Documentation.docc/Proposals/0001-v2-plugins.md

swift package lambda-init

swift package lambda-build 

swift package lambda-deploy

(and keep swift package archive for compatibility)
