google-app-engine - `go build -mod vendor` 无法使用 vendored 包

Question

将我的 Go 服务部署到 Google AppEngine(标准)时，我收到一条错误，描述未找到模块版本，但编译一切正常。

模块位于私有(private) Github 实例上，并 check out 到 vendor/。

go build -mod vendor -o/dev/null ./... 在 cloud-build-local、本地和 Google Cloud Build 中工作。github.com/company/gosystem 上存在一个名为“v1.1.0”的标签:

gosystem$ git tag
v0.0.1
v0.0.2
v0.0.3
v1.0.0
v1.1.0

grep -RI 'gosystem@' * 不报告任何内容。

最后，我通过将其添加到 go.mod 中强制使用 vendor 来完成这项工作:

replace github.com/company/gosystem => ./vendor/github.com/company/gosystem
