What went wrong?

ERROR: ContractType collision across compiler plugins
contracts are not compiled.

How can it be fixed?

refactor

[sabotagebeats]

this is also an issue in previous version 0.1.0a23 with ape-vyper 0.1.0a6 (0a7 is not compatible with a23)

[fubuloubu]

This has an easy explanation: you can't use the same name for a smart contract inside your project. Token.vy means the name ends up being the same there, and willing to bet that Token.sol just uses contract Token { ... } internally, hence same name.

Update error message so that the fix is clearer for end-users
