project.json scripts events can delete folders?

Question

I am trying to delete a folder on post compile but cant make rd or del commands to work. Is there a way to delete a folder and subfolders from the scripts events?

Answer 1

Put the commands that you need in a batch or shell file and invoke that file in the post compile step

Answer 2

Use npm and gulp task, that not depends on the OS

Add a package.json file in your project root with gulp and gulp-rimraf dependencies:

{
  "version": "1.0.0",
  "description": "your description",
  "name": "your project name",
  "readme": "yuour readme",
  "license": "Apache-2.0",
  "dependencies": {
  },
    "devDependencies": {
        "gulp": "3.9.1",
        "gulp-rimraf": "0.2.0",
    },
    "scripts": {
        "gulp": "gulp",
    }
}

Add a gulpfile.js in your project root containing the cleanup task :

/// <binding Clean='clean' />
"use strict";

var gulp = require("gulp"),
        rimraf = require("gulp-rimraf");


gulp.task("clean:js", function (cb) {
    return rimraf("path to js folder to delete", cb);
});

gulp.task("clean:css", function (cb) {
    return rimraf("path to css folder to delete", cb);
});

gulp.task("default", ["clean:js", "clean:css"]);

In your project.json, call the npm script :

{
    ...
    "scripts": {
        "precompile": "npm run gulp" // this will call the default gulp task
    },
}

For more information, you can read the doc about how to use gulp on the asp.net docs site
You can do the same using grunt instead of gulp if you want
