Task name

UseDotNet

Task version

2.232.0

Issue Description

When installing runtime 8.0.0 using the UseDotNet task I got the following error
Failed while prepending .Net Core Tool path to PATH envrionment variable. Error: {"code":"ERR_INVALID_ARG_TYPE"}

I spotted that this line of usedotnet.ts does not run as I cannot see the message in the logs. Scrolling up a bit I noticed the use of path.join that throws the error Invalid Argument when it does not receive a string. From the call here it receives a Constant defined as a path from the utilities file.

Going through Git Blame I did not see any recent changes to any of these files so I don't know if this is the cause of the issue.

[MrLuje]

Almost got the same issue with v6.x (but the runner has both 6.x & 8.x versions)

Tool to install: .NET Core sdk version 6.0.x.
Found version 6.0.417 in channel 6.0 for user specified version spec: 6.0.x
Version: 6.0.417 was found in cache.
Failed while prepending .Net Core Tool path to PATH envrionment variable. Error: {}
Finishing: Install .NET 6.0.x SDK

The worst thing on my side is that the task appears as succeed, whereas obviously nothing will work without the DOTNET_CLI_HOME env var

[nesherhh]

Any news on this? I have same error with .NET SDK 8.0.301 and UseDotNet 2.238.1

[jkonecki]

I get the following error when installing 6.x on Ubuntu 22.04.4 LTS:

Found version 6.0.33 in channel 6.0 for user specified version spec: 6.x

Here is the task definition:

- task: UseDotNet@2
  inputs:
    packageType: 'runtime'
    version: '6.x'

[AppiePau]

I have had the same issue with .NET 9.x. Here is the solution:

Have the following config in your yaml pipeline:

- task: UseDotNet@2
  displayName: 'Install .NET Core SDK'
  inputs:
    version: 9.x
    installationPath: '$(Agent.TempDirectory)/dotnet'

Then in the right top corner of your Azure (web) editor click "Variables" and add:

Name: DOTNET_CLI_HOME
Value: $(Agent.TempDirectory)/dotnet

That's it!

I do so dislike that the only way I was able to avoid this issue was by manually copying the dotnet executable (extracted from the tarball) into the /usr/local/bin folder using sudo. Both the install and the localization string messages no longer show up, and I am getting Code Coverage results.
