Managing Submodule Versions in Go
Go repositories can contain multiple submodules, each with its own go.mod file. This raises the question of how versions of submodules are managed.
Understanding Submodule Versioning
Unlike traditional submodules in git, the versions of submodules in Go are not directly tied to the versions of the parent module. They should be treated as separate modules that share a common repository.
Resolving Conflicting Versions
In the example provided, the conflict arises because the root module and a submodule have the same name. This can cause the go command to become confused when trying to resolve the location of the submodule.
Hierarchical Git Tags
Go supports hierarchical git tags to mark versions of submodules. These tags follow the following format: /path/to/submodule/vX.Y.Z. For instance, while the latest version of the vault module is 1.3.3, the latest hierarchical tag for vault/api submodule is v1.0.4.
Managing Submodule Releases
To resolve version conflicts and manage submodule releases effectively, consider the following steps:
