Incompatibility with Go 1.24?

[jachym-tousek-keboola]

After updating to Go 1.24 I'm running into this error whenever I run any go-licenses command:

$ go tool go-licenses report ./...
# github.com/google/go-licenses
vendor/github.com/google/go-licenses/save.go:125:9: cannot use func(src string) (bool, error) {…} (value of type func(src string) (bool, error)) as func(srcinfo os.FileInfo, src string, dest string) (bool, error) value in struct literal

Anyone else having this problem?

You might have added version 1 to your Go tools. Try running
go get -tool github.com/google/go-licenses/v2@latest.

Wait there is a v2? The latest tag is 1.6.0. 🤔

Edit: Ah I see. It's a pre-release. 👍 But no updates since the first alpha was released it seems.

I don't get it - why does the existence of an alpha v2 mean that v1 should break?

With go 1.25-rc1:

Error: ../../../go/pkg/mod/golang.org/x/tools@v0.12.0/internal/tokeninternal/tokeninternal.go:78:9: invalid array length -delta * delta (constant -256 of type int64)

(note: this is with v2@d01822334fba5896920a060f762ea7ecdbd086e8)

(Note: go build will work - go install will not)

(Note: https://cs.opensource.google/go/x/tools/+/refs/tags/v0.24.0:internal/tokeninternal/tokeninternal.go negative initialization of array is getting flagged. build is probably handling this scenario but install is not.)

This is strange though i would assume till the build the path of execution would be same?

After updating to Go 1.24 I'm running into this error whenever I run any go-licenses command:

@jachym-tousek-keboola Ensure that you're using the correct version of https://github.com/otiai10/copy in your go.mod file and that you don't replace it and that theres's no conflicting version.

go-licenses v1.6.0 was using https://github.com/otiai10/copy/blob/v1.6.0/options.go#L14-L15 (go.mod).
go-licenses v2 is using https://github.com/otiai10/copy/blob/v1.10.0/options.go#L17-L18 (go.mod).
