What did you do?

Install build tools from tools.go:

go install $(go list -f '{{join .Imports " "}}' tools.go)

What did you expect to see?

No error

What did you see instead?

go list errors:

tools.go:6:2: import "github.com/dmarkham/enumer" is a program, not an importable package

I realise this might not be a bug per se but it is a change of behavior over go1.20.

Thank you, wasn't even aware of this flag: -e works when used with -f.

@bcmills not quite sure why this is marked as duplicate. From what I understand the reasoning is that:

  • main packages should never have been allowed by go list
  • these errors were not consistently reported in the past (and are not reported consistently today or the referenced issue would not be open- although it seems to relate to -test only?)
  • -e allows proceeding anyway to workaround is in place.

Please correct me (only if wrong). Thank you!

The errors were previously not reported consistently. For some unknown reason, the code changes for -pgo=auto in 1.21 cause them to be reported in cases where they were previously not diagnosed.

#59186 is still open because we still don't understand why the errors were previously not reported, and we still don't know whether there are causes where they remain unreported today.
