Hello, what I have is a problem about starting my launcher to minecraft, it appers me "exit code 1"

I have the version of Java 8 update 101

I am using a computer with 64 bits (operative system)

What happens is that I made a modpack, and I tried to run it with the "YoFenix Launcher"

What is in the launcher says:

"Cliente> Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/Level
Cliente> at net.minecraft.launchwrapper.Launch.launch(Launch.java:94)
