Add echo of maven commands

[djeanprost]

In order to ease diagnose, could it be possible to echo maven command line before running it ?
thank you

I will see what I can do. This is not trivial because execa only allows access to the concatenated command after completing the process.

As of March, execa has had an improved verbose option added that allows using a full mode that outputs the command and both it's STDERR and STDOUT, which we should be able to pretty easily leverage here. 🥳
