I am trying to start a server on forge 1.8 and i get up to the point where i try to run the Forge universal.jar. when i double click the file it gives me an error box that says "The Java JAR file could not be launched. Check console for possible error messages". Please help me i really want to run a 1.8 forge server. Here is a picture of the error:

can you help me? it is for 1.8 but the same problem. here is the error message: We appear to be missing one or more essential library files. You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:190) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:499) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:374) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:25) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:12)
