1.10.2 Server: A problem occurred running the Server

[scrouthtv]

My problem is that my forge 1.10.2 (12.18.3.2185) server won't start. I have downloaded the windows installer and it downloaded some files:

Afterwards, I started the minecraft server jar, accepted the eula, and started it again. Starting the forge file wasn't working and gave me this error message:

I am running java 10:

java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

 

Searching on Google, I saw some people encountering this problem as well, but I wasn't able to find any solution to my problem. I think, the problem is, that I'm missing some files, but could somebody please provide me with instructions on where / how to get these files?

 

I know that 1.10.2 isn't the latest MC version, but as there haven't all mods made their way to 1.12 I hope that somebody could help me ?
