I'm currently working something on AWS Cloudformation which using this repo https://github.com/awslabs/goformation. Because I did some customise so I made a fork https://github.com/vrealzhou/goformation.
Now in my other project (using go module) I'm trying to using go get github.com/vrealzhou/goformation@v2.3.1 and I've got this error:
go: github.com/vrealzhou/goformation@v0.0.0-20190513073615-ff3b65adb278: parsing go.mod: unexpected module path "github.com/awslabs/goformation"
go: error loading module requirements
Does anyone know the reason and how to solve this problem? Thanks
You can use replace in your go.mod to use a fork instead of the upstream version. That way, you can make whatever modifications you need to the code without having to update the module path or import paths.
To be specific, in this case, you can do the following in your go.mod (I tested this by forking the repo, making a small change, and confirming it showed up):
require github.com/awslabs/goformation v1.4.1
replace github.com/awslabs/goformation => github.com/vrealzhou/goformation master
The first time you build or test, master will be replaced by the latest pseudo-version for your fork to make sure you get repeatable builds. The replace requires a specific version for the replacement.
