[caseif]

It appears Cauldron does some weird renaming when it shades libraries. I'll look into writing a fix, but no promises. This is a very difficult issue to circumvent without creating a build especially for Cauldron.

[Cody-Wolf]

But pass my test ,TTT-0.6 can run on Cauldron.

[caseif]

Yes, but version 0.6 did not rely on Guava whereas Steel (the new backend as of 0.8) does.

[Cody-Wolf]

You can try imitating TTT0.6 to fix the bug. I think may be the problem of Steel.(In version 0.7, you change Guava to Steel.And after version 0.6,it can't run on Cauldron)

[caseif]

That's not quite how it works. Steel is a minigame engine which TTT uses as of version 0.8.x, whereas Guava is a utility library that Steel happens to use. However, because of the way Minecraft Forge is built, Guava doesn't always seem to be accessible, hence why you're having this issue.

[Cody-Wolf]

Can you develop new versions of TTT for Cauldron?

[Cody-Wolf]

Because version 0.6 is too old. And it doesn't have the new version of the many functions.

[caseif]

As I've said, I'll look into resolving this issue, but a fix could potentially be complex so I can't guarantee that it will see a fix in the near future.

[caseif]

Have you tried recompiling Cauldron and testing to see if the issue still occurs?

[caseif]

Support for Minecraft 1.7.x will be dropped in TTT v0.11, so I'm marking this issue as wontfix.
