Webpack publish issue

Tools/version
Angular 4.4.3
Webpack 3.6.0
DotNet Core 2.0
NPM 5.3.0

We have added the ng2 smart table to our applications it works great but we are running into issues wile publishing the build to prod
webpack --config webpack.config.vendor.js (this works fine and generate the vendor.js and css) but while running
**webpack --env.prod is where it gets struck and does not throw any error.**

The issue is with the AOTPlugin in the webpackconfig I guess.

Please suggest a solution.

Thanks!
