Redis – How to embed go.mod & go.sum in go 1.16

I want to embed a sub module directory in parent module, but golang remind me that pattern tpl/api_new/*: cannot embed file tpl/api_new/README.md: in different module

I know that I can delete go.mod & go.sum and then run "go mod init && go get -u" when the new project is generated.

The bottom is the file tree and the embed variable, is there anything others I can do to embed go.mod & go.sum?
Thanks~

//go:embed tpl/api_new/*
var apiNew embed.FS

    is there anything others I can do to embed go.mod & go.sum?

    Each module within a repository is stored separately within the module cache. By design, the presence of a go.mod file in a subdirectory causes that entire subtree to be completely pruned out of the outer module.

    If you really need the individual files in tpl/api_new to be accessible to the module in the parent directory, then you can either:

    1. remove the inner go.mod and go.sum files to put the source files all in the same module, or
    2. export the embed.FS data from some package within the …/tpl/api_new module (perhaps an internal package), and import that package in the parent-directory module in order to access that data programmatically.
