Anything Else?

i use the arclight

Hybrids aren't supported.

Don't use arclight. Use any of Spigot, Paper, or Forge.

Thanks for your answer,but I want to know how to solve it.

To reiterate:

Hybrids aren't supported.

Unless someone PRs support, no.

Thank you,I see,and is it possible that it can use arclight in the future?
