Hey everyone. 

forge keeps crashing in eclipse. Though this isn't crashing in IntelliJ can anyone help me with this? It might be something small.

I get thrown this exception 

Error: Unable to initialize main class net.minecraftforge.userdev.LaunchTesting

Caused by: java.lang.NoClassDefFoundError: com/mojang/authlib/exceptions/AuthenticationException
