Javascript Question

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?

Answer

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.
