I cannot install any of the programms above.

Spigot:

• • • Error, this build is outdated ***
    • Please download a new build as per instructions from https://www.spigotmc.org/go/outdated-spigot ***
    • Server will start in 20 seconds ***

However, the server does not start after 20 seconds. It says "Agree to the Eula", but there is no Eula-file in the directory. No, the name/path doesn't contain special characters. The exact output is in the spigot-error.txt.

Craftbukkit:

Same error.

BuildTools:

I tried the guide in the wiki, but it gives me the error: 

I tried the suggested command below

I tried the given command (java -Xmx1024M -jar BuildTools.jar), but the error stays the same. I also tried every variation of that command I could find on here, but nothing works.

The only thing that changed is with the command: 

You can see the output in Buildtools-error.txt.

I don't know what to change or what to do. Please help.

P.S. I don't know the version I am supposed to enter above, as /version does not work for me.
