Missing essential libraries for forge server

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 successfu

Use the installer.

I did use the installer and it didn't work.

If you did then you moved things around and screwed it up.

The libraries folder needs to be there and include the libraries that the installer downloads.

I'm using the latest forge and I have the same problem. It seems to me that the forge server jar isn't loading the launchwrapper library as it should. Manually setting the classpath gives me another error. Probabbly because I forgot to include some other libraries.

[LexManos]

Ah that is actually a legitimate bug, just a oversight in our switch to the gradle system.

I've fixed it and it will be in the next build.

But pre-gradle builds {such as the one this guy is using} should be fine.

[king_capybara]

So what should I do to fix it then?

[LexManos]

Use the recomended build.
