Not able to generate APK file

Bug Report

Problem

I am trying to build and android version of my ionic application. Sadly I am not able to generate an APK file.

I am running the command “ionic cordova build android”. The sub task “cordova.cmd build android” stops with:

config file undefined requested for changes not found at C:\Users\d060445\university\Team Project\Tracktivity\moveit\platforms\android\undefined, ignoring
config file undefined requested for changes not found at C:\Users\d060445\university\Team Project\Tracktivity\moveit\platforms\android\undefined, ignoring
The "path" argument must be of type string. Received type undefined

running “cordova.cmd build android --verbose” shows:

I have already tried several times to remove the android platform and add it again to my project, but the issue still persists.

Version of cordova: $ cordova -v 9.0.0 (cordova-lib@9.0.1)

I found the error. The problem is with Node version. this piece of code is where error occurs

function recursivelyFindFiles (dir, extension) {
    if (!fs.existsSync(dir) || !extension) return [];

    const files = fs.readdirSync(dir, { withFileTypes: true })
        .map(entry => {
            const item = path.resolve(dir, entry.name);

            if (entry.isDirectory()) return recursivelyFindFiles(item, extension);
            if (path.extname(entry.name) === `.${extension}`) return item;
            return false;
        });

    return Array.prototype.concat(...files)
        .filter(file => file !== false);
}

withFileTypes parameter is only available in Node 10.10.0 version (https://nodejs.org/api/fs.html#fs_fs_readdirsync_path_options) In my case I am using 10.4.0 Node version so this parameter is not available, and for that entry is a string value (entry.name is undefined).

Therefore, updating Node version to 10.10.0 we solve the problem.

I don’t know if this Node version dependency is normal or not, but I didn’t find which Node version dependency is needed with this plugin version.

recursivelyFindFiles is located in ProjectBuilder.js (\platforms\android\cordova\lib\builders\ProjectBuilder.js), line 74.

I think it would be a good idea to reflect that required version in package.json
