If i publish to the server from visual studio the site works

Looks like there is an issue with the jenkins server. Anybody known what needs to be updated?

Hi,

This is a known issue with Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.6. Downgrading to 1.0.5 fixed this for me.

You can even update it to latest 1.0.8. It should fix the issue.

Please check the below url for other options.

Hi. I am using 1.0.8 and it works on my computer. It works when i do a manual deploy to dev test server (Normally jenkins server does this).

The problem is that the CopyRoslynCompilerFilesToOutputDirectory does not run after compile is done.

MSBuild.exe xxx.sln /p:Configuration=Release

When i built this way i see a CopyRoslynCompilerFilesToOutputDirectory and my bin gets the files

CopyFilesToOutputDirectory:
  wwwroot -> D:\Jenkins\workspace\XXX - Build Gerrit\xxx\wwwroot\bin\wwwroot.dll
CopyRoslynCompilerFilesToOutputDirectory:
  Creating directory "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\wwwroot\bin\roslyn".
  Copying file from "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\packages\Microsoft.Net.Compilers.2.4.0\build\..\tools\csc.exe" to "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\wwwroot\bin\roslyn\csc.exe".
  Copying file from "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\packages\Microsoft.Net.Compilers.2.4.0\build\..\tools\csc.exe.config" to "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\wwwroot\bin\roslyn\csc.exe.config".
  Copying file from "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\packages\Microsoft.Net.Compilers.2.4.0\build\..\tools\csc.rsp" to "D:\Jenkins\workspace\xxx - Build Gerrit\xxx\wwwroot\bin\roslyn\csc.rsp".

There is more files here here but i did not include all

The problem is visible when i add DeployOnBuild=true;DeployTarget=Package (the CopyRoslynCompilerFilesToOutputDirectory does not trigger and the package does not work).

MSBuild.exe xxx.sln /p:Configuration=Release;DeployOnBuild=true;DeployTarget=Package;_PackageTempDir=' + project.buildDir + '/publish;PackageLocation=' + project.buildDir + '/xxx-Release-%CHANGESET_BUILD_IDENTIFIER%.zip'

It did a reinstall/update of Build Tools for Visual Studio 2017 (make sure i had latest msbuild)

If i compile first and then run the command above the package it works (the zip package bin folder contains the roslyn folder with files)

Is this a Bug in msbuild?

<p>It looks like we need a change in the Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props file under packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.8\build\net45</p> <p>I added back in a target from the 1.0.5 version by adding back in</p> <p>&lt;Target Name="IncludeRoslynCompilerFilesToItemGroup" AfterTargets="ResolveAssemblyReferences" &gt;<br />&lt;ItemGroup&gt;<br /> &lt;None Include="@(RoslyCompilerFiles)" Condition=""&gt;<br /> &lt;Link&gt;%(RoslyCompilerFiles.Link)&lt;/Link&gt;<br /> &lt;CopyToOutputDirectory&gt;PreserveNewest&lt;/CopyToOutputDirectory&gt;<br /> &lt;/None&gt;<br />&lt;/ItemGroup&gt;</p> <p>before</p> <p>&lt;Target Name="CopyRoslynCompilerFilesToOutputDirectory" ... /&gt;</p> <p>and publishing should work again.</p> <p>Let me know if you face any other issues , when you are updating this.</p> <p></p>

I guess this code only works on 1.0.5. I think i found a better way.

At the moment i just run MSBuild.exe twice (added a todo to remove this when it works again). One for build - MSBuild.exe xxx.sln /p:Configuration=Release (triggers copy roslyn files). Then i call MSBuild.exe again for creating package/zip file.

It works. I will revisit this commit and try to fix it in a couple of months.
