Default task exits prematurely

[slavafomin]

Hello!

Thank you for this great module!

However, I have an issue when default task is terminating without waiting for all the tasks to properly complete.

Here's my gulpfile.ts:

import {Gulpclass, Task, SequenceTask} from 'gulpclass';
import * as gulp from 'gulp';
import * as del from 'del';
import * as ts from 'gulp-typescript';

const tsProject = ts.createProject('tsconfig.json');

@Gulpclass()
export class Gulpfile {

  @Task()
  clean () {
    return del(['./dist/']);
  }

  @Task()
  compile () {
    return gulp.src('./src/**/*.ts')
      .pipe(tsProject()).js
      .pipe(gulp.dest('dist'))
    ;
  }

  @Task('migrations:copy')
  migrationsCopy () {
    return gulp
      .src('./src/application/migrations/**/*.pgsql')
      .pipe(gulp.dest('./dist/application/migrations/'))
    ;
  }

  @SequenceTask()
  build () {
    return ['clean', ['compile', 'migrations:copy']];
  }

  @Task()
  default () {
    return ['build'];
  }

}

When I run each task individually it works correctly.

Here's the output of the default task:

$ gulp
[13:25:25] Using gulpfile ./gulpfile.js
[13:25:25] Starting 'default'...
$

My gulpfile.js looks like suggested in the docs:

eval(require('typescript').transpile(require('fs').readFileSync('./gulpfile.ts').toString()));

What could be the problem?

Thanks!

As I found out in the FAQ:

Why? Because the array you are returning is what task is doing, not a task dependencies as you wish:

@Task("default", ["clean", "compile", "build"])
default() {
}

However, your example in the docs contradicts this:

@Task()
default() { // because this task has "default" name it will be run as default gulp task
    return ["build"];
}

I suggest to update the README to make this use case more clear.

actually its better to use ts-node then this .js hack. Can you provide a PR for the changes you propose?

When I try to use ts-node I'm getting the following:

$ gulp
[09:47:50] Failed to load external module ts-node/register

there were rules how to use ts-node... try to install it both globally and locally and dont forget to putl --save-dev flag

[slavafomin]

It works after installing locally, thanks. Sadly, this is not mentioned in the docs.
