> What you can do to prevent the long outputs is just use: {{--batch-mode}}

> {code}
> So based on the naming of {{\-\-no-transfer-progress}} which is a bit
> misleading because the transfer progress output has already been supressed by
> using {{--batch-mode}}.
> For Maven 4 we could think about a more cleaner way:
> * {{--batch-mode}} will not change anything
> * {{--no-transfer-progress}} will prevent the output of {{Progress (3):
> 237/733 kB | 172/225 kB | 172/184 kB}} (which will really represent the
> function related to the name).
> * {{--no-download-output}} could suppress the output as of using {{-ntp}} in
> Maven 3.X
> That would be a bit more consistent
