Lesson 6 : Deploying Simple Storage from hardhat

[usman-2000]

Hey fellas!
I am facing an issue while i write a command : yarn hardhat run scripts/deploy.js
the error is :
"HardhatError: HH700: Artifact for contract "SimpleStorage" not found."

Anyone can help me with this, would be greatly appreciated.

@usman-2000 It did not find the artifacts for SimpleStorage contract, either you have not compiled the contract or it is not compiled correctly. Run these commands npx hardhat clean and then npx hardhat compile

Please I have the same challenge but it doesnt solve it for me.

1. npx hardhat clean
2. npx hardhat compile

Thanks ~ Sir~

Look at @Ajoffcials reply too. Just change the contract name from lock to simplestorage within the code itself.

make sure your contracts name is the same as the name in your artifacts directories'
solidity

contract SimpleStorage {
    uint public unlockTime;
    address payable public owner;

    event Withdrawal(uint amount, uint when);

    constructor(uint _unlockTime) payable {
        require(
            block.timestamp < _unlockTime,
            "Unlock time should be in the future"
        );

        unlockTime = _unlockTime;
        owner = payable(msg.sender);
    }

    function withdraw() public {
        // Uncomment this line, and the import of "hardhat/console.sol", to print a log in your terminal
        // console.log("Unlock time is %o and block timestamp is %o", unlockTime, block.timestamp);

        require(block.timestamp >= unlockTime, "You can't withdraw yet");
        require(msg.sender == owner, "You aren't the owner");

        emit Withdrawal(address(this).balance, block.timestamp);

        owner.transfer(address(this).balance);
    }
}

        emit Withdrawal(address(this).balance, block.timestamp);

        owner.transfer(address(this).balance);
    }
}

}
in deploy.js file

const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage")

note the name of the contract must be the same as artifacts
