> in Go you just put in the code URL (git repo / branch / sha1) and you have it

It seems you're thinking of the old Go dependency management.

The current Go dependency management, Modules, means that you put in the unique name of the Module (which is its URL) and the Semver-compatible version. Then go mod can resolve the exact code you need.

Sure, it's still source-code based, so you don't need to build a JAR file. Of course, that also means you can't have external dependencies that you pull in - you must have everything required to build your go module in that source code.

Go mod also checks version incompatibilities based on Semver and chooses the lowest specific version which matches everyone's Semver dependency specification.

Your source-control server must also know how to act as a go mod repository (it needs to respond to some go mod specific HTTP calls, as far as I could tell).

Now, when you want to publish a new version in Go, you don't build and publish a specific build to some extra repository. Instead, you need to tag some commit in your repo with a Semver version.

If you want to publish a new major version, you need to do much more than that, since any version higher than v1 will impact the name of your package in import statements in Go code (import "github.com/mymod/mypack" will become import "github.com/mymod/mypack/v2" in any code using your module, including internally).
