Gulp：无依赖性的同步性 [英] Gulp: Synchronicity without dependency

问题描述

我已经定义了各种构建任务（ scripts ， style ， jade 等）以及清理任务，删除所有构建的文件。

我想确保构建任务在清理任务之前不运行， 但是我也希望能够在不清理的情况下运行构建任务。

即我想：

gulp.task（'build'，['clean'，'scripts'，'style'，'jade']） ;

要开始运行脚本， style 和 jade 之后 clean 已完成，但

  gulp.task（'watch'，function（）{
 
 gulp.watch（'path / to / stylus'，['css' ]）; 
 
}）; 
  

不应触发 clean 如果 css 依赖于 clean 。

  ... 
 var sequence = require（'run-sequence'）; 
 
 gulp.task（'dev'，['css'，'js'，'html']）; 
 
 gulp.task（'watch'，function（）{
 
 gulp.watch（src.css，['css']）; 
 gulp.watch （src.js，['js']）; 
 gulp.watch（src.html，['html']）; 
}）; 
 
 gulp.task（'default'，function（done）{
 
 sequence（'clean'，'dev'，'watch'，done）; 
 }）;

请阅读：

这是一个临时解决方案，直到orchestrator更新为支持非依赖性的有序任务。

I'm migrating my build system over to gulp, and have encountered a problem:

I have defined various build tasks (scripts, style, jade, etc), as well as a clean task that removes all of the built files.

I want to make sure that the build tasks don't run before the clean tasks, BUT I also want to be able to run the build tasks without cleaning first.

i.e. I want:

gulp.task('build', ['clean', 'scripts', 'style', 'jade']);

To only start running scripts, style and jade after clean has finished, but

gulp.task('watch', function(){

  gulp.watch('path/to/stylus', ['css']);

});

Should not trigger clean to be run, which would be the case if css had a dependency on clean.

解决方案

I've faced the same problem:

...
var sequence = require('run-sequence');

gulp.task('dev', ['css', 'js', 'html']);

gulp.task('watch', function() {

    gulp.watch(src.css, ['css']);
    gulp.watch(src.js, ['js']);
    gulp.watch(src.html, ['html']);
});

gulp.task('default', function(done) {

    sequence('clean', 'dev', 'watch', done);
});

Please, read:

This is intended to be a temporary solution until orchestrator is updated to support non-dependent ordered tasks.
