Bring back support for non go modules projects to v1.1+

[Bobgy]

In v1.1, we made a breaking change of no longer supporting non go modules managed projects per discussions in #70. However, #125 seems to show that some users are still using GOPATH.

Creating this issue to track users who are still using GOPATH mode.
Please thumbs up if this affected you or comment about your scenario.

JFYI, you can keep using go-licenses v1.0.0 before any further actions are taken.

go install github.com/google/[email protected]

@Bobgy this is impacting our GH actions using the following config:

jobs:
  golicense-pr-scan:
    runs-on: ubuntu-latest
    steps:
      - name: install-git
        run: sudo apt-get install -y git

      - name: install-golicenses
        run: GOBIN=/usr/local/bin go install github.com/google/go-licenses@latest

      - name: checkout
        uses: actions/checkout@v3

      - name: Configure git for private modules
        env:
          TOKEN: ${{ secrets.TOKEN }}
          USER: ${{ secrets.USER }}
        run: git config --global url."https://${USER}:${TOKEN}@github.com".insteadOf "https://github.com"

      - name: Set up Go
        uses: actions/setup-go@v3
        with:
          go-version: 1.21

      - name: golicense-scan
        run: |
          go-licenses check ./... --ignore github.com/myorg

We can't downgrade to v1.0.0 as we require --ignore. Any suggestions?

Simply changing go-licenses check ./... --ignore github.com/myorg to go-licenses check --ignore github.com/myorg ./... fixed this for me 🤦🏼‍♂️

I ran into this today when trying to do a license scan of the https://github.com/crossplane/crossplane project.

go install github.com/google/go-licenses@latest
git clone https://github.com/crossplane/crossplane.git
cd crossplane
go-licenses csv ./...

That shows many error messages like the following in the output:

Looks like it's mostly the standard library. I was able to get some license scan output after running go install github.com/google/[email protected]. Is there a different way I should be invoking latest to work successfully?

Legend, that same fix worked for me too

EDIT: Sorry, the opposite is true for me lol (I had ./... last, now I have it first)- I am at least unblocked now though.

I have the same issue as reported by @jbw976 above. I have a go.mod-backed proprietary project, and running go-licenses on it spits out a bunch of errors for the stdlib imports.

go-licenses report ./...
