Failed with: quic-go doesn't build on Go 1.18 yet.

[CompuRoot]

xcaddy: from development branch
go version go1.18 linux/amd64

The same issue as it was in 4216

xcaddy successfully compiled, but command xcaddy list-modules failed with error on following:

go/pkg/mod/github.com/lucas-clemente/quic-go@v0.23.0/internal/qtls/go118.go:5:13: cannot use "quic-go doesn't build on Go 1.18 yet." (untyped string constant) as int value in variable declaration

The latest stable version of Caddy was released before Go 1.18 was released, so it doesn't support it. We made fixes on the master branch to support Go 1.18, so if you absolutely need to build with 1.18, you should build from master for now. Otherwise, please downgrade to 1.17 in the meantime until Caddy's next stable release.

If you build with docker and can't easily downgrade your go version, caddy:2.4.1-builder worked fine

[francislavoie]

@tyler71 Use v2.5.1. Not v2.4.1. That's an outdated version.

Either way, this is a long-since-fixed issue.
