Description
What happened?
Required binaries are installed using go install, which relies on the predefined GOBIN. But when codegen tools are invoked in the script, the resolved gobin variable might not be pointing to the right location, as it's only resolving the environment variable ($GOBIN) or fall back to $GOPATH/bin explicitly, missing the value which might be set for go env GOBIN without exporting it.
What did you expect to happen?
The correct location is used, and so the binary is invoked (or the desired version of it).
How can we reproduce it (as minimally and precisely as possible)?
Fails with custom GOBIN

❯ go env -w GOBIN=$(mktemp -d)
