Go module with multiple paths

#php editor Zimo introduced: Recently, the module management tool in the Go language has ushered in a new function-multipath module. The introduction of this feature allows developers to more flexibly specify the module path when using Go modules. In the past, developers could only install modules in fixed paths, resulting in more complex module dependencies. Now, the emergence of multi-path modules provides developers with more choices, making module management more convenient and flexible. Developers can install modules in different paths according to project needs, thereby achieving better module management and version control. The introduction of this new feature will further improve the development efficiency and convenience of Go language.

Question content

I have a go module that is mirrored to multiple locations. One is in gitlab and the other is in bitbucket. When trying to base it on the new gitlab location I get:

go: gitlab.com/company/[email protected]: parsing go.mod:
module declares its path as: bitbucket.org/company/core
but was required as: gitlab.com/company/core

I know why this happens, but how do I define my go.mod as "or"?

Solution

Short answer: You can't.

But all may not be lost...

If you have code in the location referenced by the module path and in a different location that for some reason you prefer to download from, you can configure git alias to redirect the reference from the specified module path to all Required download source:

git config --global --add url."https://<download path>".insteadof "https://<module path>"

Aliases do not have to be completely replaced. You can use aliases to replace the prefix on any module path. So if you host a number of modules on server and the path covers all of these modules (as long as the repository name is the same). For example, we use this to create "friendly" module paths for modules hosted in a local azuredevops server git repository, for example:

git config --global --add url."https://tfs.myorg.com/myorgcollection/_git".insteadof "https://tfs.myorg.com"

Our module will then be able to identify itself as

tfs.myorg.com/somemodule.git

, but when

go get tries to get this git, it will Find it in https://tfs.myorg.com/myorgcollection/_git/somemodule.git (

.git

suffix is ​​necessary azure devops feature ) To be honest, I haven't tried this on a completely different server just to "rewrite" the path on the same server, but in principle it should work. So in your case:

git config --global --add url."https://gitlab.com/company/".insteadof "https://bitbucket.org/company/"

Since this applies to things at the

git

level, as far as

go is concerned, it's still fetched from bitbucket.org even though git gitlab.com will be accessed in the background. That is when you go get

you need to quote the

declared module path:

go get bitbucket.org/company/core

The only downside to this is that you need to configure the alias on any/all workstations (and build machines) that require go get

from anywhere other than the location declared in the module path.
