Failed to install libraries [Forge server installation]

[ArlyssFR]

Hello there,

Before read, please considere that i've read the red pinned message about the "old installers currently not working".
This message is about the 1.11.2-13.20.1.2588 .

i'm encountering the exact same problem since days, with "forge-1.11.2-13.20.1.2588-installer.jar" :
with or without firewall, also checked my connection, tested on 2 PCs.

I execute the jar in CMD (with or without admin rights), with this format :
"java -Djava.net.preferIPv4Stack=true -jar forge-1.11.2-13.20.1.2588-installer.jar"
and i always get this log :
