Последний токен Zeppelin SampleCrowdsale.sol перемещен вне контракта?

Действительно новичок в Solidity, но я следовал этому руководству: https://blog.zeppelin.solutions/how-to-create-token-and-initial-coin-offering-contracts-using-truffle-openzeppelin-1b7a5dae99b6

Только я использовал последний zeppelin-solidity( 1.7.0), который, согласно этому коммиту , вынес создание токена за пределы контракта краудсейла.

Если у меня есть следующее TestTokenCrowdsale.sol:

pragma solidity ^0.4.18;

import "zeppelin-solidity/contracts/crowdsale/validation/CappedCrowdsale.sol";
import "zeppelin-solidity/contracts/crowdsale/distribution/RefundableCrowdsale.sol";
import "zeppelin-solidity/contracts/crowdsale/emission/MintedCrowdsale.sol";
import "zeppelin-solidity/contracts/token/ERC20/MintableToken.sol";


/**
 * @title SampleCrowdsaleToken
 * @dev Very simple ERC20 Token that can be minted.
 * It is meant to be used in a crowdsale contract.
 */
contract SampleCrowdsaleToken is MintableToken {

  string public constant name = "Sample Crowdsale Token"; // solium-disable-line uppercase
  string public constant symbol = "SCT"; // solium-disable-line uppercase
  uint8 public constant decimals = 18; // solium-disable-line uppercase

}


/**
 * @title SampleCrowdsale
 * @dev This is an example of a fully fledged crowdsale.
 * The way to add new features to a base crowdsale is by multiple inheritance.
 * In this example we are providing following extensions:
 * CappedCrowdsale - sets a max boundary for raised funds
 * RefundableCrowdsale - set a min goal to be reached and returns funds if it's not met
 *
 * After adding multiple features it's good practice to run integration tests
 * to ensure that subcontracts works together as intended.
 */
contract SampleCrowdsale is CappedCrowdsale, RefundableCrowdsale, MintedCrowdsale {

  function SampleCrowdsale(uint256 _openingTime, uint256 _closingTime, uint256 _rate, address _wallet, uint256 _cap, MintableToken _token, uint256 _goal) public
    Crowdsale(_rate, _wallet, _token)
    CappedCrowdsale(_cap)
    TimedCrowdsale(_openingTime, _closingTime)
    RefundableCrowdsale(_goal)
  {
    //As goal needs to be met for a successful crowdsale
    //the value needs to less or equal than a cap which is limit for accepted funds
    require(_goal <= _cap);
  }

}

Вот мой 2_deploy_contracts.js:

const SampleCrowdsale = artifacts.require(“./TestTokenCrowdsale.sol”)

module.exports = function(deployer, network, accounts) {
    const openingTime = Date.now()/1000|0 + 120;
    const closingTime = openingTime + (3600 * 1 * 1); // *1 hour *1 days
    const ethRate = new web3.BigNumber(100);
    const wallet = accounts[0];
    const cap = 100000000000000000000;
    const goal = 200000000000000000000;

deployer.deploy(SampleCrowdsale, openingTime, closingTime, ethRate, wallet, cap, goal);
};

Когда я запускаю turffle migrate --reset, я получаю следующую ошибку:

~/src/test-token $ truffle migrate --reset

Что мне не хватает?
