For some reason it is trying to use jline's internal Preconditions which is not present on the client, instead of Guava's which is what is imported and used as a dependency. Not exactly sure why this is happening but I'll try to figure it out.

[parlough]

I made a pull request to blood's 1.10.2 branch here: https://github.com/bloodmc/TerrainControl/pull/1

Once that gets merged a version compiled from there should work.

[parlough]

If anyone else has this issue the latest version of blood's 1.10.2 fork should be good to compile without this issue. You can find the 1.10.2 branch here: https://github.com/bloodmc/TerrainControl/tree/1.10.2

The Forge version is more or less taken over by @PG85 - see his fork called OpenTerrainGen. I don't think this will be fixed by me.
