[Pkg-matrix-maintainers] Bug#1003505: node-matrix-js-sdk: FTBFS with webpack5: Unknown option '--output'

[Caleb Adepitan]

Source: node-matrix-js-sdk
Version: 9.11.0+~cs9.9.16-1
Severity: important
Tags: ftbfs
User: pkg-javascript-devel at alioth-lists.debian.net
Usertags: webpack5

Hi,

We are starting to build against webpack5 in experimental and the 
package needed for local build is webpack and node-webpack-source from 
experimental.
During a test rebuild, node-matrix-js-sdk was found to fail to build in 
that situation.

Relevant part (hopefully):

tsc --project Xbase-x
grunt --no-color --base=Xloglevel concat uglify
 >> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?
 >> Local Npm module "grunt-coveralls" not found. Is it installed?
 >> Local Npm module "grunt-jasmine-node" not found. Is it installed?
 >> Local Npm module "grunt-contrib-jshint" not found. Is it installed?
 >> Local Npm module "grunt-contrib-watch" not found. Is it installed?
 >> Local Npm module "grunt-contrib-qunit" not found. Is it installed?
 >> Local Npm module "grunt-contrib-connect" not found. Is it installed?

 >> Local Npm module "grunt-saucelabs" not found. Is it installed?
 >> Local Npm module "grunt-preprocess" not found. Is it installed?
 >> Local Npm module "grunt-contrib-clean" not found. Is it installed?

Running "concat:dist" (concat) task

Running "uglify:dist" (uglify) task

Done.
