Webpack incremental build does not work

[Leekao]

According to Webpack5 documentation in order to utilize incremental build I need to pass cache object with type: "filesystem" however that does nothing when I pass it through Grunt-webpack and the documentation for Grunt-webpack refer to cache as a Boolean.

If anyone in the future wonders how I resolved this issue the solution for me was to remove grunt-webpack and to run webpack from cli using grunt-shell and it indeed builds incrementally.

Makes sense. Grunt suppress output and input a lot more than needed. Like error handling.
