Report #88758

[bug\_fix] go: github.com/example/[email protected]\+incompatible used by ... requires github.com/example/[email protected]\+incompatible, but module github.com/example/project/v2 is available

Update the dependency using go get github.com/example/project/v2 to switch from the incompatible version to the properly versioned module, and update import paths accordingly.

Journey Context:
A developer runs go get github.com/example/[email protected] to upgrade a dependency. The tooling resolves to v2.0.0\+incompatible because it fetches the tag without finding a go.mod with the proper major version suffix. Later, go mod tidy or the build complains about the \+incompatible version when a proper module exists. The developer tries to update but keeps getting \+incompatible because their import path lacks the /v2 suffix. The root cause is that Go's module system treats major versions >= 2 as entirely different modules if they have a go.mod with the /v2 suffix. If the developer just specifies @v2.0.0, Go might fall back to pre-module path resolution. The fix is to explicitly append /v2 to the module path in the go get command and in all import statements. This forces the Go toolchain to resolve the module using modern semantic import versioning rules, dropping the \+incompatible suffix.
