publish_source fails with deployed library

[sschuldenzucker]

Environment information

• brownie Version: 1.21.0
• ganache-cli Version: x.x.x (irrelevant)
• solc Version: 0.7.6
• Python Version: 3.12.4
• OS: osx

What was wrong?

I'm using a contract (say MyContract) that is deployed with the library also being deployed (not compiled into the contract). The library is in libraries/. When I want to verify this, I'm getting the following crash:

❯ brownie console --network bsc-main

VaultsDevProject is the active project.
Brownie environment is ready.

  File "brownie/project/flattener.py", line 44, in path_to_name
    return "contracts/" + pth.split("/contracts/")[1]
IndexError: list index out of range

Guessing from the code, it seems that brownie expects my library at contracts/, where it is not.

How can it be fixed?

Use a better method for tracing dependencies that hard-coding "/contracts/" as a separator. Actually include all the dirs where source files might be.

Hmm, I quickfixed this but now there's another error "cannot determine location of using".
