Error - Access is denied - deployment to Azure App Services

问题

We use automatic deployment process in Azure by KUDU scripts and by today we see strange error in Azure deployment center:

Command dotnet publish (and also 'dotnet build') returns:

MSBUILD : error MSB1025: An internal failure occurred while running MSBuild.
Unhandled exception. System.ComponentModel.Win32Exception (5): Access is denied.
System.ComponentModel.Win32Exception (5): Access is denied.

   at Microsoft.Build.CommandLine.MSBuildApp.Execute(String[] commandLine)
Failed exitCode=-532462766, command=dotnet publish "D:\home\site\repository\
...

Details:

• there is automatic deployment process by KUDU script
• app is .NET Core application, .csproj has target framework: netcoreapp2.2

Issue probably will be on Azure side, because we did't do any bigger change in the project. Has anybody same/similar issue?

回答1:

We had the same issue and after investigation we found that:

• Azure applied new 'dotnet' version 3.1.301 and this version of SDK throws that error (your version you can check by commnad 'dotnet --version')
• by command 'dotnet --list-sdks' you can see all installed SDKs
• then we simple used previous version (in our case v3.1.202)
• the easiest way how to tell exact version of dotnet sdk is by global.json

Example: global.json

{
  "sdk": {
    "version": "3.1.202"
  }
}

And file must be in 'working directory', and KUDU script has working directory here D:\home\site\repository

When your deployment was OK on previous version of dotnet SDK, than this should definitely help.
