I'm trying to run a 1.7.10 forge server but when I try to run the forge file nothing happens.

 

C:\Users\nghgi\Desktop\server>java -jar forge-1.7.10-10.13.4.1614-1.7.10-universal.jar
A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

1.7 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
