You must build several version of craftbukkit first to compile. These should be put into the spigot directory.

The file names should start with spigot and end with .jar for our build script to find it automatically!

1. Grab buildtools

From here: https://www.spigotmc.org/wiki/buildtools/

2. Create requires jars

You can see the versions required in the build.sh file.

3. Grab other jars not supported by buildtools

You also need to download:

• https://github.com/Sarabveer/CraftBukkit-Spigot-Binary/tree/master/spigot-1.7.5-R0.1
• https://github.com/Sarabveer/CraftBukkit-Spigot-Binary/tree/master/spigot-1.7.9-R0.3
• https://github.com/Sarabveer/CraftBukkit-Spigot-Binary/tree/master/spigot-1.7.2-R0.4
• https://github.com/Sarabveer/CraftBukkit-Spigot-Binary/tree/master/spigot-1.7.10-1.8-R0.1

4. Done!

As long as they are all in the spigot directory it will work fine.
