Problem

I get the following error after running $ truffle migrate --reset:

Environment

• Truffle v4.0.1 (core: 4.0.1)

• Solidity v0.4.18 (solc-js)

• EthereumJS TestRPC v6.0.3 (ganache-core: 2.0.2)

Migrations file

My 1_initial_migration.js file looks like:

var Migrations = artifacts.require("./Migrations.sol");
var TestCrowdsale = artifacts.require("./TestCrowdsale.sol");

module.exports = function(deployer) {
   deployer.deploy(Migrations);
   deployTestCrowdsale(deployer);
};

function deployTestCrowdsale(deployer) {

   const accounts = web3.eth.accounts;

   const startTime = latestTime();
   const endTime = startTime + duration.days(45);
   const rate = 2500;
   const goal = web3.toWei(250, 'ether');
   const cap = web3.toWei(4000, 'ether');
   const wallet = accounts[0];

   return deployer.deploy(TestCrowdsale, startTime, endTime, rate, wallet);

}

function latestTime() {
  return web3.eth.getBlock('latest').timestamp;
}

const duration = {
   seconds: function (val) { return val; },
   minutes: function (val) { return val * this.seconds(60); },
   hours: function (val) { return val * this.minutes(60); },
   days: function (val) { return val * this.hours(24); },
   weeks: function (val) { return val * this.days(7); },
   years: function (val) { return val * this.days(365); },
};

Crowdsale file

TestCrowdsale contract uses the Zeppelin Solidity framework. My TestCrowdsale.sol file looks like:

pragma solidity ^0.4.18;

import 'zeppelin-solidity/contracts/crowdsale/Crowdsale.sol';

contract TestCrowdsale is Crowdsale {

   function TestCrowdsale(uint256 _startTime, uint256 _endTime, uint256 _rate, address _wallet)
      Crowdsale(_startTime, _endTime, _rate, _wallet)
      public
      {
   }

}

truffle.js file looks like:

module.exports = {
   networks: {
     development: {
       host: "localhost",
       port: 8545,
       network_id: "*" // Match any network id
     }
  }
};

Answer 1

The origin of the issue is because you're trying to deploy the contract from the file migrations/1_initial_migration.js that is supposed to be used only for the deployment of Migration.sol.

To deploy your contracts, you need to create a file in migrations/2_deploy_contracts.js that contains the deployment part of TestCrowsale.sol

migrations/1_initial_migration.js

var Migrations = artifacts.require("./Migrations.sol");
module.exports = function(deployer) {
   deployer.deploy(Migrations);
};

migrations/2_deploy_contracts.js

var TestCrowdsale = artifacts.require("./TestCrowdsale.sol");

module.exports = function(deployer) {
   deployTestCrowdsale(deployer);
};

function deployTestCrowdsale(deployer) {

   const accounts = web3.eth.accounts;

   const startTime = latestTime();
   const endTime = startTime + duration.days(45);
   const rate = 2500;
   const goal = web3.toWei(250, 'ether');
   const cap = web3.toWei(4000, 'ether');
   const wallet = accounts[0];

   return deployer.deploy(TestCrowdsale, startTime, endTime, rate, wallet);

}

function latestTime() {
  return web3.eth.getBlock('latest').timestamp;
}

const duration = {
   seconds: function (val) { return val; },
   minutes: function (val) { return val * this.seconds(60); },
   hours: function (val) { return val * this.minutes(60); },
   days: function (val) { return val * this.hours(24); },
   weeks: function (val) { return val * this.days(7); },
   years: function (val) { return val * this.days(365); },
};

I tried on my side and the deployment go through :

Compiling ./contracts/Migrations.sol...
Writing artifacts to ./build/contracts

Using network 'development'.

Answer 2

Check any abstract/interface methods are being implemented correctly. I get this issue, where it compiles but won't deploy, when I fail to implement abstract/interface methods correctly in inheriting contracts.

Edit: Also check all the require statements in the Crowdsale constructor will pass. Maybe try with hardcoding a startTime definitely in the future in the deployment script eg 1999999999.

Answer 3

This can happen when you're using wrong initialization parameters in your Truffle migration file. As an example, let's consider the following simplified contract:

pragma solidity ^0.4.19;

contract Lease {

  function Lease(
                address _owner,
                address _tenant,
                uint _startDate,
                uint _fee,
                uint _deposit)
    public {
    require(_owner != _tenant);
    require(_startDate > now);
    require(_fee > 0);
    require(_deposit >= fee * 2);
  }
}

In order to deploy it, assume you're using the following migration file:

var Lease = artifacts.require("./Lease.sol");

module.exports = function(deployer) {
  var owner = '0xf17f52151ebef6c7334fad080c5704d77216b732';
  var tenant = '0xc5fdf4076b8f3a5357c5e395ab970b5b54098fef';
  var startDate = 1522904400;
  var fee = 1000000000000000000;
  var deposit = 2000000000000000000;
  deployer.deploy(Lease, owner, tenant, startDate, fee, deposit);
};

When you run truffle migrate --reset you get the aforementioned error. Can you tell what's wrong?

In this case, startDate is assigned to a unix time in the past, which causes the second require statement in the contract constructor to fail.

Unfortunately, Truffle isn't specific enough about this kind of errors yet, so you have to be very careful about them.
