@Maxime Garcia or @Nicolas Vannieuwkerke could you take a look ? Also, I would like to do some reformating on the repository make

mvn checkstyle:check

or

mvn spotless:check

pass. However the underscore in

<http://nf_core.nf|nf_core.nf>.test.utils

is not compatible, would you prefer

<http://nf.core.nf|nf.core.nf>.test.utils

or

nfcore.nftest.utils

? This also impact the folder architecture (1 dot = 1 folder).

I prefer less dots personally

But let's do this in a separate PR
