如何从Gruntfile.js获取最新的提交哈希？

Question

What I'm trying now is to use shelljs, but for some reason shell.exec('git rev-parse HEAD') just hangs.

This is my code:

function getLatestCommit() {
    return shell.exec("git rev-parse HEAD", {
        silent: true,
    }).output.trim().substr(0, 7);
}

Does anyone know any other way to achieve this?

I'm working on windows...

shell.exec uses a callback. You're passing a parameter to it, but not utilizing the callback:

var shell = require('child_process');

function getLatestCommit() {
    shell.exec("git rev-parse HEAD", { silent: true }, function(error, stdout, stderr) {
        console.log(error, stdout);
    });
}
getLatestCommit();
