const requireDir = require('require-dir');
const gulp = require('gulp');

// Require all tasks in gulp/tasks, including subfolders
requireDir('./build/tasks', {recurse: true});

gulp.task('default', ['lint', 'check_license'], () => {
	// This will only run if the lint task is successful...
});

screen shot of the error I'm new in the hyperledger community, I tried to test fabric-sdk-node project that I cloned from github. When I try 'gulp test' it hsows me an error "Task 'test' is not in your gulpfile". how can I solve it ? this is my gulpfile.js

Solution

I played around with that require-dir package for awhile. The only way I could get it to work was:

// in './build/tasks/test.js'

const gulp = require('gulp');
const sass = require('gulp-sass');

// note the use of gulp.task syntax, **not** function test()

gulp.task('test', function() {
  console.log("in test task");
  return gulp.src('./scss/*.scss')
    .pipe(sass())
    .pipe(gulp.dest('./dist'));
});

// in 'gulpfile.js'

const requireDir = require('require-dir');
const gulp = require('gulp');

// Require all tasks in gulp/tasks, including subfolders
requireDir('./build/tasks', { recurse: true });

gulp.task('default', gulp.series('test'));  // note I have gulp v4 on my machine

This does run the test task successfully, transpiling the scss file in this case.

Despite the fact that I am running gulp4 I had to use the gulp.task('test') syntax to get it to work. It would not work if the test task was defined like so:

function test() {
  console.log("in test function");

  return gulp.src('./scss/*.scss')
    .pipe(sass())
    .pipe(gulp.dest('./dist'));
};

which I would normally use. (With gulp.task('default', gulp.series(test));)

Are your tasks created as gulp.task('sdfsdfsdfs')? I assume they are since you are using the gulp.task('default', ['lint', 'check_license'] type of syntax.
