[datho7561]

What were you expecting to happen?

Nothing (build succeeds with v4)

Please give us a sample of your gulpfile

Additional information

I think it's good that sourcing files from a folder that doesn't exist causes the build to fail, but I think the error message should be more clear and less noisy.

Thanks for the report. I think I know where to fix this but it'll take some time.

We'll probably move this issue over to the glob-stream repository, as that's where the bug exists.

I also hit this trying to upgrade to Gulp 5.
Gulp 4 used to silently skip missing directories, is there any plan to support an option to include this behaviour in 5? I’d like to not have to test every directory exists before trying to copy it as I’m not responsible for the sources that may or may not exist

@tinogo it's a bug. We'll fix it when we have time.
