npx hardhat run check: raise error, exit code stays 0

[codekoriko]

Version of Hardhat

2.22.2

What happened?

I'm using the hardhat-solhint plugin, when the litting process raise error, the exit code stays the 0, therefor command chaining with && don't break, which is a problem

Minimal reproduction steps

Running the linter as mentioned in the doc:

npx hardhat check && echo 'Error Code: '$? 

An error arise during the linting but Exit Code stays 0

    8:1  error    Unexpected import of console file

I was able to reproduce this locally, by taking a new typescript sample project, adding the solhint plugin, running solhint --init and updating the config to:

{
  "extends": "solhint:recommended"
}

On running npx hardhat check we don't get a non-zero exit code:

Because of this I think protofire/solhint#554

Opened the issue protofire/solhint#572

Thanks @madlabman, we will keep this open to track the issue coming in on the hardhat-solhint plugin.

@kanej just a heads up this was fixed in Solhint 5.0.1 🚀

[kanej]

Just note that upgrading to Solhint 5.0.1 would equate to a major version bump in the hardhat-solhint plugin.
