Angular 6 universal, .net template , unable to publish due to uglifyjs-webpack-plugin

Question

I'm using Angular 6 universal with .net template and unable to publish the site. I'm getting the following error:

C:\Program Files\dotnet\sdk\2.1.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Publish.targets(140,5): error MSB3030: Could not copy the file "C:\projects\stash\serversiderendering\serverSideRendering\ClientApp\node_modules.cache\uglifyjs-webpack-plugin\content-v2\sha512\12\98\ca644f17078ac9e4c0fcda9c49f1ce74cd50192b7a404d45d26adabcc8f8fa22ca38476a913d2b79930a104b1d8fe9d2400a1dbc65e6951943067e92ebc5" because it was not found. [C:\projects\stash\serversiderendering\serverSideRendering\serverSideRendering.csproj]

Something with copying uglifyjs-webpack-plugin in .cache folder.

I went through the tutorial how to enable universal: Use the Angular project template with ASP.NET Core. The template comes with Angular 5 I updated Angular and cli to 6 so I had to do some changes:

My angular.json file looks like:

Answer 1

I was only able to fix my issue by turning off optimization on server side in angular.js

     "server": {
      "builder": "@angular-devkit/build-angular:server",
      "options": {
        "outputPath": "dist/server",
        "main": "src/main.server.ts",
        "tsConfig": "src/tsconfig.server.json",
        "optimization": false
      }
    }

Answer 2

I was able to fix the issue by excluding the .cache folder from publishing in csproj task PublishRunWebpack like this:

<PropertyGroup>
    ...
    <SpaRoot>Client</SpaRoot>
    ...
</PropertyGroup>

<Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
<!-- Include the newly-built files in the publish output -->
<ItemGroup>
  <DistFiles Include="$(SpaRoot)\dist\**" />
  <DistFiles Include="$(SpaRoot)\node_modules\**; $(SpaRoot)\dist-server\**" 
             Exclude="$(SpaRoot)\node_modules\.cache\**" 
             Condition="'$(UseServerSideRenderer)' == 'true'" />
  <ResolvedFileToPublish Include="@(DistFiles->'%(FullPath)')"
                         Exclude="@(ResolvedFileToPublish)">
    <RelativePath>%(DistFiles.Identity)</RelativePath>
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </ResolvedFileToPublish>
</ItemGroup>
