如何一个接一个地运行吞咽任务

Question

in the snippet like this:

gulp.task "coffee", ->
    gulp.src("src/server/**/*.coffee")
        .pipe(coffee {bare: true}).on("error",gutil.log)
        .pipe(gulp.dest "bin")

gulp.task "clean",->
    gulp.src("bin", {read:false})
        .pipe clean
            force:true

gulp.task 'develop',['clean','coffee'], ->
    console.log "run something else"

In develop task I want to run clean and after it's done, run coffee and when that's done, run something else. But I can't figure that out. This piece doesn't work. Please advise.

It's not an official release yet, but the coming up Gulp 4.0 lets you easily do synchronous tasks with gulp.series. You can simply do it like this:

gulp.task('develop', gulp.series('clean', 'coffee'))

I found a good blog post introducing how to upgrade and make a use of those neat features: migrating to gulp 4 by example
