[Ethereum] The reason for “Could not find artifacts for” in truffle

soliditytruffle

Any ideas about the reason for the following error from truffle? The contract is from the solidity docs.

Truffle.js –

//var Set = artifacts.require("./Set");
var Consumer = artifacts.require("./Consumer");
var Infofeed = artifacts.require("./Infofeed");
//var med1 = artifacts.require("./med1");
module.exports = function(deployer) {
  //deployer.deploy(Set);
  //deployer.link(Set, d3);
  deployer.deploy(Consumer);
  deployer.deploy(Infofeed);

};

Code – 

pragma solidity ^0.4.18;

contract InfoFeed {
    function info() public payable returns (uint ret) { return 42; }
}

contract Consumer {
    InfoFeed feed;
    function setFeed(address addr) public { feed = InfoFeed(addr); }
    function callFeed() public { feed.info.value(10).gas(800)(); }
}

Filename – Consumer.sol

Output –

Writing artifacts to ./build/contracts

Using network 'development'.

I got the same problem just now, but I solved it in this way.

  • After your compilation, go to your_folder_location\build\contracts folder.

  • Then you will see a JSON file which not related to your contract file.

  • Just rename that JSON file same as your contract file. ( most probably that JSON file related your folder name )

  • But after that you can see the renamed file as well as the original file too, both files in same location. Don't worry.

That's it.
