How to compile and deploy a third-party contract?

[Jeiwan]

Hello!

In a test, I want to deploy the ERC20 contract from @openzeppelin/contracts. How can I do that via ethers.getContractFactory() without creating a local contract that inherits from the ERC20 contract? In other words, how to compile that contract and load its artifact via ethers.getContractFactory()?

Thanks

Ended up creating empty dependency-contracts that only import third-party contracts. This make Hardhat compile them so they can be used in tests.

Hey @Jeiwan, sorry for not answering before.

You are correct that that's a possible solution. Another solution is to use the hardhat-dependency-compiler plugin
