Webpack compilation ignores source change

I use Webpack + Gulp with build-watch style like explained here (mode 2). Occasionally, Webpack ignores the change of JS source. Gulp script is very simple.

gulp.task("webpack:build-dev", function(callback) {
   // run webpack
   devCompiler.run(function(err, stats) {
       // Handle error
       callback();
   });
});

Complete example is on Github. After change of index.js, the bundle should reflect the change. It does not happen on first time, then it is working fine. I started from real-life project, and here the pattern was different: 1st, 3rd, 5th etc change was ignored. Looks as Webpack bug, any other ideas before posting the issue to developers?

Solution

  • I've posted a bug to Webpack developers (https://github.com/webpack/webpack/issues/3137). It is not reproducible in Webpack 2 (currently in beta) and probably will not be fixed for Webpack 1.x.
