Can't activate multiple jar plugins via --plugins

[MarieLataretu]

Hi there,

I try to activate multiple local jar plugins (nf-test 0.8.4):

nf-test test my-test.nf.test --plugins path/to/my/nft-plugin.jar,path/to/my/nft-plugin2.jar

However, the list is not split:

Plugin 'path/to/my/nft-plugin.jar,path/to/my/nft-plugin2.jar' not found.

(I was assuming the same as --plugins [email protected],[email protected])
