Report #46456

[bug\_fix] go: github.com/foo/[email protected] requires github.com/baz/[email protected] but github.com/baz/[email protected] is required

Run go get github.com/baz/[email protected] to update the indirect dependency in go.mod to the higher required version, followed by go mod tidy.

Journey Context:
A developer adds a new dependency and runs go build. The build fails with a version conflict. They try deleting go.mod and go.sum and running go mod init again, which makes it worse. The rabbit hole involves manually editing go.mod to remove the offending version, only to find go build puts it back. The root cause is Go's minimal version selection \(MVS\). If github.com/foo/bar requires v1.3.0 and another dependency requires v1.2.0, MVS selects v1.3.0. However, if the go.mod file explicitly lists v1.2.0 \(perhaps from a previous go get\), the build fails because the requirement graph is inconsistent. The fix works because go get updates the go.mod to satisfy the MVS algorithm, ensuring the selected version meets all requirements.
