Thousands of times when I tried to launch it but didn't make sense.

It responsed this:(I HAVE used bat,simply doubleclick forge-1.12.2-14.23.5.2854.jar and forge-1.12.2-14.23.5.2854-universal.jar,and my eula was set to true)

 

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException
