controller-gen fails when path is not wildcard

[AndreiBarbuOz]

Running the controller-gen works when using wildcards:

./bin/controller-gen crd paths="./pkg/apis/foo/v1alpha1/..." output:stdout

but fails when running on a specific file:

./bin/controller-gen crd paths="./pkg/apis/foo/v1alpha1/bar_types.go" output:stdout

with output:

Error: load packages in root "/home/baz/go/src/github.com/org/project/pkg/apis/foo/v1alpha1/bar_types.go": err: fork/exec /usr/local/go/bin/go: not a directory: stderr:

@AndreiBarbuOz would this be covered by #864?

[AndreiBarbuOz]

yes @sbueringer , looks like it. I'll close this issue as a duplicate of #837
