There is a small nuisance with Visual Code and Go, but is mainly related to the most recent release of go 1.11.x and the newly introduced module system. The go builder creates a folder called 'auto' for cached builds, which can be cleaned / deleted via 'go clean -cache'.
Visual Code seems to be confused when executing tests, if such a directory is present, and complains about missing dependencies:
/home/user/.golang/src/github.com/stretchr/testify/assert/assertions.go:20:2: could not import github.com/pmezard/go-difflib/difflib (open auto/4c/4cb1f0f2c9f328e3cade99998704759897fd4e530af38db25c85cdc253c1f1a0-d: no such file or directory)
is there any possibility to fix this? Or is it just another setting I forgot to make?
