Trying to get Forge to work for a few of my clients, I am getting this set of errors repeatedly. I am sure I am overlooking something, but I would appreciate it if we could be pointed in the correct direction. We are using Multicraft.

 

21.07 21:45:47 [Multicraft] Looks like a crash, check the server console. Return value: 1

Thanks a whole lot!

I get the same results. Any workarounds?

Install the server and all related libraries correctly.

That's why we have a installer.

-.-

I downloaded and executed the installer executable. That created the files for me. I have never used any other method to install forge servers. They just all worked. Not this time, though.

These files were created by the 1.7.10 stable Installer-Win executable:

• forge-1.7.10-10.13.0.1180-universal.jar
  
• minecraft_server.1.7.10.jar
  
• libraries/ (folder):
  
  • com/
    
  • lzma/
    
  • net/
    
  • org/
    

 

So, how did a simple run of the installer cause user error here?

 

This is my console printout, since I did not get a log.

By the way, I tried 1187 latest first. When that didn't work either, I went to recommended.

I don't know but somehow you did it.

log4j is inside minecraft_server.1.7.10.jar, as long as it's there and you run the server correctly it'll find it.

You can manually add the libraries if you're running in the wrong folder using the standard method of adding to the java classpath.

That's the problem. I just looked in the jar, and it is indeed corrupt. Premature end of archive reached. I did not download that. Forge did it. So, what is the problem with it check the download (MD5SUM or something) and giving a useful error?

I have to download it manually now, correct?

 

Update:

After downloading the server jar file, things have started normally. Thanks for the hint, LexManos.
