Setting the OutDir in a isolated function causes the build to fail.

snarodev commented 7 months ago

Setting the OutDir option with msbuild causes a Isolated Function build to fail.

How to replicate:

Create a new isolated function project (either with Visual Studio or func init LocalFunctionProj --worker-runtime dotnet-isolated --target-framework net6.0)
Do a restore
Run msbuild "path/to/the/solution" /p:OutDir="some/other/output/folder" in the Developer Command Prompt

The build then fails. When OutDiris not specified, the extensions.jsonfile is created in the Temp folder and then copied, but when OutDir is specified the extensions.json file is created in the output folder, but then the next step then looks for the file in the .azurefunctions folder.

Example output of the relevant build log parts without the OutDir option (Command msbuild "C:\Users\jms\Desktop\DeleteNow\FunctionApp1\FunctionApp1.sln" -> Build works):

Interesting.. I got the same error while using Azure Pipelines VSBuild:

Same for me while using Azure Pipelines VSBuild with dotnet-isolated --target-framework net7.0. I tried with Microsoft.Azure.Functions.Worker.Sdk 1.13.0 and 1.16.0

Is there any resolution for this issue? I've spent most of today trying to find some resolution for this. I have uninstalled both .NET and Rider, reinstalled them, and tried creating a brand new Functions solution only to be met with this error. I am unable to work on my Functions project with this error.

Mr-Technician commented 5 months ago

I'm not certain what step of the process fixed this issue, but I was able to resolve the error after these steps:

Clear nuget cache
Uninstall Rider
Uninstall Visual Studio
Reboot
Install Visual Studio
Install Rider
Reboot
Attempt to build project (still failed)
Clear nuget cache again

i ran into what appears to be the same problem but without the involvement of the /p:OutDir parameter.

I am facing the same issue when building function app project targeting .NET 8 in isolated model in Azure DevOps pipeline. The project build fine in local environment but gives this error in Azure DevOps pipeline. I have added steps for installing both .NET 6 and .NET 8 in the ADO pipeline but still facing the same issue. What is the solution to this problem?

Here is the error message : ##[error]C:\Users\VssAdministrator.nuget\packages\microsoft.azure.functions.worker.sdk\1.17.2\build\Microsoft.Azure.Functions.Worker.Sdk.targets(190,9): Error MSB4018: The "EnhanceExtensionsMetadata" task failed unexpectedly. System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\a\1\b\publish_output.azurefunctions\extensions.json'.

@pkpaul5 I worked around the problem by not setting an output directory. The build artifacts will then be placed in the default location bin\...\.

pkpaul5 commented 3 months ago

@markuspalme Thanks for your suggestion. I am able to work around the problem by not setting output directory.

I was able to build in Azure Pipelines with 1.17.2. I was having issues also but got it resolved.

Hope this helps! https://github.com/Azure/azure-functions-dotnet-worker/issues/2291#issuecomment-2057575535
