Mains Plugin does not work with FILES() DSL

[ichbestimmtnicht]

The generated svc.New() call does not include enough http.FileSystem calls.

Example Errors with 10 Files() endpoints:

not enough arguments in call to staticsvr.New
have (*static.Endpoints, "goa.design/goa/v3/http".ResolverMuxer, func(r *"net/http".Request) "goa.design/goa/v3/http".Decoder, func(ctx context.Context, w "net/http".ResponseWriter) "goa.design/goa/v3/http".Encoder, nil, nil)
want (static.Endpoints, "goa.design/goa/v3/http".Muxer, func("net/http".Request) "goa.design/goa/v3/http".Decoder, func(context.Context, "net/http".ResponseWriter) "goa.design/goa/v3/http".Encoder, func(context.Context, "net/http".ResponseWriter, error), func(ctx context.Context, err error) "goa.design/goa/v3/http".Statuser, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem, "net/http".FileSystem)compilerWrongArgCount

Checked the corresponding code in case I missed something in my DSL setup:

plugins/mains/templates/main.go.tpl

Lines 121 to 125 in bd0a993

	{{- if .HasWebSocket }}
	{{ .SrvVar }} := {{ .GenHTTPPkg }}.New({{ .EpVar }}, mux, goahttp.RequestDecoder, goahttp.ResponseEncoder, nil, nil, upgrader, nil)
	{{- else }}
	{{ .SrvVar }} := {{ .GenHTTPPkg }}.New({{ .EpVar }}, mux, goahttp.RequestDecoder, goahttp.ResponseEncoder, nil, nil)
	{{- end }}

Thanks for the report, this is now fixed in head.
