We are noticed in our automated builds that the "npm run publish" step to build the angular front end is very slow.. Its taking upwards of 15 minutes (usually around 5 minutes). When building locally it looks like maybe the source map generation is the issue... But when I try to avoid source map generation (--no-sourcemap) then the build fails with the following.
Are there any known ways to get that build step sped up?

@catapult you can check angular-cli's github repo for performance suggestions. I also couldn't see the error you are getting when using --no-sourcemap.

Sorry I forgot to include the build output..
So background I have tweaked the package.json publish command so that I can get around some of the build performance issues (per some angular threads I looked at before posting here).. The last optimization I was trying was to add --no-sourcemap to the ng build command.. Below is the output from the build agent.
The specific error is "Unknown option: '--sourcemap'"

Hi,
The default value of --source-map is true. So to disable sourcemaps use the below command
ng build --source-map=falseSimilarly --prod avoids creating sourcemaps by default but if you want to create then just use --source-map in the end to create sourcemaps.
--sourceMap=false<a class="postlink" href="https://github.com/angular/angular-cli/issues/10676">https://github.com/angular/angular-cli/issues/10676</a>
