Question

尝试从nodeJS运行gradlew：

const spawn = require('child_process').spawn;
const path = require('path');

function run() {

    var path_dir = path.resolve('./../movies/VanillaApp/android');

    var options = {
        cwd: path_dir
    };

    const ls = spawn('gradlew', ['assembleRelease'], options);

    ls.stdout.on('data', (data) => {
        console.log(`stdout: ${data}`);
    });

    ls.stderr.on('data', (data) => {
        console.log(`stderr: ${data}`);
    });

    ls.on('close', (code) => {
        console.log(`child process exited with code ${code}`);
    });

}



module.exports = {
    run: run
};

终端等价：

> ./gradlew assembleRelease

得到：

events.js:154
throw er; // Unhandled 'error' event
^

Error: spawn gradlew ENOENT

更新：

我设法使用child_process.exec而不是spawn运行。

Answer 1

我自己偶然发现了这个问题，并设法使用--project-dir命令行选项gradlew与spawn一起运行：

var taskDone = this.async();

grunt.util.spawn({
    cmd: "my/relative/path/gradlew",
    args: ["clean", "--project-dir", "my/relative/path"],
    opts: {
        stdio: "inherit"
    }
}, function (error, result) {
    if (error) {
        taskDone(false);
    } else {
        taskDone();
    }
});

我使用的是 react-native，所以我只是在我的根目录中创建了一个脚本文件夹，并添加了一个名为 cleanBuild.js 的文件，内容如下：

#!/bin/node

const { exec } = require("child_process");
const currentOs = require("./getOs");

const os = currentOs();

//===================================================================
function cleanBuild() {
    console.log("\nCleaning project build...");

    exec(`cd android && ${os === 'darwin' ? './gradlew clean' : 'gradlew clean'} && cd ..`, (error, stdout, stderr) => {
        if (error) {
            console.log(`\nFailed to clean build: ${error.message}`);
            return;
        }
        if (stderr) {
            console.log(`\nFailed to clean build: ${stderr}`);
            return;
        }
        console.log(`\nBuild cleaned successfully: \n${stdout}`);
    });
}

//===================================================================
cleanBuild();

现在我可以运行它了：

node ./scripts/cleanBuild.js

从nodejs运行gradlew
