Task 'clean-dist' is not in your gulpfile

[marviobezerra]

I'm trying to use your code, to do it I created these files:

package.json

{
    "name": "test",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "devDependencies": {
        "del": "^2.2.1",
        "gulp": "^3.9.1",
        "gulpclass": "^0.1.1",
        "typescript": "^1.8.10"
    }
}

tsconfig.json

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": true,
        "suppressImplicitAnyIndexErrors": true
    }
}

gulpclass.ts

import { Gulpclass, Task } from "gulpclass/Decorators";

let gulp = require("gulp");
let del = require("del");

@Gulpclass()
export class Gulpfile {
    @Task("clean-dist")
    clean(cb: Function) {
        return del(["./dist/**"], cb);
    }
}

gulpfile.js

eval(require("typescript").transpile(require("fs").readFileSync("./gulpclass.ts").toString()));

So, I execute:

gulp clean-dist

The output is:

    Using gulpfile d:\Temp\Test\gulpfile.js
    Task 'clean-dist' is not in your gulpfile
    Please check the documentation for proper gulpfile formatting
```***

I don't know what I'm doing wrong, can someone help me?

In order to us the transpile with gulpfile.js you need to npm install --save-dev fs for require('fs')
