<!-- Hi, thanks for contributing! Please make sure you read our CONTRIBUTING guide. Also, add tests and the respective documentation changes as well. --> <!-- If applied, this commit will... --> The gomod pipe will skip if the Go version does not support modules. <!-- Why is this change being made? --> I tried to use goreleaser to build a project with Go v1.8.7 and it failed on `loading go mod information` step. The Go version used doesn't support `go list -m`. The build failed with the following error: ``` • loading go mod information ⨯ release failed after 0s error=failed to get module path: exit status 2: flag provided but not defined: -m usage: list [-e] [-f format] [-json] [build flags] [packages] List lists the packages named by the import paths, one per line. ... ``` <!-- # Provide links to any relevant tickets, URLs or other resources --> ...
