Nodejs branches test doesn't execute by command "grunt fileName" - node.js

Question

I have a problem with my nodejs git branches test. This is the code:
var exec = require('child_process').exec;
var request = require('request');
var cheerio = require('cheerio');
var async = require('async');
var currentDir = ""; // dir
var getBranches = "git for-each-ref --sort=-committerdate refs/remotes/origin/ --format='%(refname:short)'";
var getAuthors = "git for-each-ref --sort=-committerdate refs/remotes/origin/ --format='%(committername)'";
var branches = [];
var errorBranches = [];
var authors = [];
var manager = [];
var result = [];
var fs = require('fs');
var openedBranches = "";
var outFile = 'BranchesTest-results.xml';
var failuresFound = false;
function eliminateDuplicates(arr) {
'use strict';
var i,
out = [],
obj = {};
for (i = 0; i < arr.length; i++)
obj[arr[i]] = 0;
for (i in obj) {
if (obj.hasOwnProperty(i))
out.push(i);
}
return out;
}
function showBranchesStats(branches, cb) {
'use strict';
console.log("in showBranchesStats method\n");
var branchesName = [];
var committers = [];
var temp = [];
var j = 0,
k = 0;
for (var i = 0; i < branches.length; i++) {
var filter = branches[i].match(/(md|dr)[_\-](\d+)/i);
if (filter !== null) {
filter = filter[1] + '-' + filter[2];
temp[j] = authors[i];
branchesName[j++] = filter;
}
else {
if (!branches[i].match(/(develop|master|HEAD)/ig))
errorBranches[k++] = branches[i];
}
}
var obj = {};
for (i = 0; i < branchesName.length; i++)
obj[branchesName[i]] = 0;
for (i in obj) {
if (obj.hasOwnProperty(i))
committers.push(temp[branchesName.indexOf(i)]);
}

request('SERVERNAME' + branchesName[i] + '?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel#issue-tabs', function (error, response, html) {
if (!error && response.statusCode === 200) {
var $ = cheerio.load(html);
try {
var data = $('.actionContainer:contains("Closed")');
if (data.length > 0) {
//var _manager = ('not(.twixi-wrap)', data).last().children().eq(0).children().children().eq(0).text();
var _manager = committers[i];
var _hasClosed = ('not(.twixi-wrap)', data).last().find(".activity-new-val").text().indexOf("Closed");
if (_manager && _hasClosed) {
var flag = false;

}
this.check = function () {

var funcs = [
function (cb) {
console.log('started 1');
exec(getAuthors, {cwd: currentDir}, function (error, stdout, stderr) {
console.log('started 1.1');
if (stderr) {
console.log('stderr: ' + stderr + "\n");
failuresFound = true;
cb();
}
else {
authors = stdout.split('\n');
console.log("Authors has been received\n");
cb();
}
if (error !== null) {
console.log('Execution command error: ' + error + "\n");
failuresFound = true;
cb();
}
});
},
function (cb) {
console.log('started 2');
exec(getBranches, {cwd: currentDir}, function (error, stdout, stderr) {
console.log("started 2.1");
if (stderr) {
console.log('stderr: ' + stderr + "\n");
failuresFound = true;
cb();
}
else {

console.log("Going to showBranchesStats method\n");
showBranchesStats(branches, cb);
}
if (error !== null) {

cb();
}
});
}
];
console.log('async.waterfall');
async.waterfall(funcs, function () {
console.log("Execution finished\n");
return !failuresFound;
});
};
it' all works just perfect locally, but when i'm trying to run it in command line or on Jenkins like this:
grunt test_Branches
something wrong happens & i get this log:
+ npm i
+ grunt test_Branches
[4mRunning "test_Branches" task[24m
Execution started
async.waterfall
Done, without errors.
Help, pls!

I resolved the problem. The solution is here.
You need rightly use asynchronous functions.
