GoMod: go list -deps error: no matching files found

[mawl]

Hey,

We have an issue with the GoMod Package Manager

10:35:45.499 [DefaultDispatcher-worker-1] ERROR org.ossreviewtoolkit.analyzer.managers.GoMod - Resolving GoMod dependencies for path 'go.mod' failed with: 
IOException: Running 'go list -deps -f {{with .Module}}{{.Path}} {{.Version}}{{end}} ./...' in '/builds/some-go-app' failed with exit code 1:
XXXXXX.go:10:12: pattern some.file: no matching files found

Content of XXXXXX.go

//go:generate cp ../../../some.file .
//go:embed some.file

some.file ist generated during build of another component in the project.

We don't want to run "go generate/go build" as a prequisite for ort. So, are there other ways to get this working?

Cheers,
Marco

@mawl would you be able to share a minimal example to reproduce this issue?
Also which go version have you been using? Have you run it in most recent ORT docker?

@fviernau here is a small example: gomod-embed-non-existing-file.zip - i'm no go pro, but I can build it by running:

compile:
  image: golang:latest
  stage: build
  script:
    - mkdir -p mybinaries
    - go generate hello-world.go
    - go build -o mybinaries hello-world.go
  artifacts:
    paths:
      - mybinaries

ort version is: https://github.com/oss-review-toolkit/ort/tree/6de32461bd9f9d20de8550c56af94839498b425a

As a workaround I use following script before running oss review toolkit, which removes the go:embed directive from relevant files (Leaving // as a comment)

grep -rl --include \*.go --exclude-dir=vendor "go:embed" . | xargs sed -i 's/go\:embed//g'
