Gulp-rev-collector doesn't work properly - gulp

Question

I don't understand what's wrong with this code. When I run it for the first time, rev_collector doesn't work. I mean: 'rev' and 'clean' works great, but css file name in index http didn't change ('rev_collector').
BUT it works properly when I start it again.
var gulp = require('gulp'),
less = require('gulp-less'),
rev_append = require('gulp-rev-append'),
rev = require('gulp-rev'),
revCollector = require('gulp-rev-collector'),
gutil = require('gulp-util'),
rimraf = require('rimraf'),
revOutdated = require('gulp-rev-outdated'),
path = require('path'),
through = require('through2');
gulp.task('rev', function(){
gulp.src('./src/less/*.less')
.pipe(less())
.pipe(rev())
.pipe(gulp.dest('./www/css/'))
.pipe(rev.manifest())
.pipe(gulp.dest('./src/manifest/'));
});
gulp.task('rev_collector', ['rev'], function(){
return gulp.src(['./src/manifest/**/*.json', './www/index.html'])
.pipe(revCollector({
replaceReved: true
}))
.pipe(gulp.dest('./www/'));
});
function cleaner() {
return through.obj(function(file, enc, cb){
rimraf( path.resolve( (file.cwd || process.cwd()), file.path), function (err) {
if (err) {
this.emit('error', new gutil.PluginError('Cleanup old files', err));
}
this.push(file);
cb();
}.bind(this));
});
}
gulp.task('clean', ['rev_collector'], function() {
gulp.src( ['./www/**/*.*'], {read: false})
.pipe( revOutdated(1) ) // leave 2 latest asset file for every file name prefix.
.pipe( cleaner() );
return;
});
gulp.task('rev_all', ['rev', 'rev_collector', 'clean']);

Today, I met the same problem.
After I got nothing from this page, I searched a lot.
I fount my problom came from the order the files loaded.
So I use a new plugin:
var runSequence = require('run-sequence');
then, I rewrite the load code:
gulp.task('default',['build']);
gulp.task('build', function (done) {
runSequence(
['clean'],
['images'],
['statcstyles', 'staticjs'],
['scripts'],
['styles'],
['html'],
done);
});
The code make sure that revCollector will always loaded after manifest create.
Then my problem solved.
I hope it helps you.
