Using two times the same filename will lead to corrupted compilation artifacts

[montyly]

• I've opened a support ticket before filing this issue.

Issue

If there are two files with the same name, the compilation artifacts will only contain one of the .json, preventing the analysis from third parties tool (such as Slither - see crytic/slither#1176)

Steps to Reproduce

See the example in crytic/slither#1176

Expected Behavior

After running truffle compile, there should be two IERC721Receiver.json file in build/contracts

Actual Results

Due to the compilation artifacts filenames structure, only one file is generated (the second one is overwritten)

Environment

Truffle v5.5.11 (core: 5.5.11)
Ganache v^7.0.4
Solidity - 0.8.13 (solc-js)
Node v16.13.0
Web3.js v1.5.3

@montyly Thank you for the report. This is a known limitation at present, the contract name (not file name) needs to be unique. We have a long-standing open issue for this, please see #1087. Closing this for duplication and hopefully, we will address the original issue soon.
