You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=2.1.0&arch=x64&rid=osx.11.0-x64
##[error]Error: The process '/usr/local/bin/dotnet' failed with exit code 150
Finishing: GitVersion

Our pipeline is defining the task as following:

         - task: GitVersion@5
            inputs:
              runtime: 'core'
          - bash: |
              echo 'build number: $(build.buildNumber)'
              exit

Expected Behavior

The newer version of .net core should be used.

Actual Behavior

The old version 2.1.0 is used instead.

Possible Fix

Steps to Reproduce

Context

Your Environment

Azure DevOps pipeline task: GitVersion@5.

• Version Used: GitVersion@5
• Operating System and version (Windows 10, Ubuntu 18.04): Using vmImage: macos-11
• Link to your project:
• Link to your CI build (if appropriate):

I am seeing the same. Setting it to use dotnetframework / mono seems to be a workaround.

From my side set runtime: 'full' saved my day

[shatodj]

So we found 2 ways of fixing that issue:

1. Adding UseDotNet@2 as the first step in a job like this

         - task: UseDotNet@2
           inputs:
             packageType: 'sdk'
             version: '2.1.x'

2. Replace GitVersion task with 2 separated tasks gitversion/setup@0 and gitversion/execute@0

         - task: gitversion/setup@0
           inputs:
             versionSpec: '5.x'
         - task: gitversion/execute@0

Same here, currently adding the:

      - task: UseDotNet@2
            inputs:
              packageType: 'sdk'
              version: '2.1.x'

workaround, but a migration to newer dotnet versions would be preferable

@shatodj https://marketplace.visualstudio.com/items?itemName=gittools.gitversion was deprecated in favor of https://marketplace.visualstudio.com/items?itemName=gittools.gittools. Please you the GitTools bundle that contains GitVersion and not GitVersion

[mc0re]

@arturcic Moving to GitTools didn't fix the problem. I still get this dependency on 2.1.0, and even installing dotnet SDK 2.1.300 does not help.

[arturcic]

@mc0re can you post here the portion of the yaml that installs and then runs the GitVersion from the GitTools bundle

[mc0re]

I have created this template for the purpose:

parameters:
- name: gitversion_config_path
  displayName: Path to "GitVersion.yml" from the .sln file
  type: string
  default: 'GitVersion.yml'

- name: gitversion_version
  displayName: Version of the tool to use
  type: string
  default: '5.x'

- name: gitversion_dotnet
  displayName: GitVersion requires 2.x and 3.x .NET SDKs installed for its execution
  type: object
  # Needs Microsoft.NETCore.App version exactly 2.1.0, which is in SDK 2.1.300
  default: ['2.1.300', '3.1.419']

steps:
- task: gitversion/setup@0
  displayName: 'Setup GitVersion ${{ parameters.gitversion_version }}'
  inputs:
    versionSpec: ${{ parameters.gitversion_version }}

- ${{ each version in parameters.gitversion_dotnet }}:
  - task: DotNetCoreInstaller@0
    displayName: 'Install .NET Core SDK ${{ version }} for GitVersion'
    inputs:
      version: ${{ version }}

- task: gitversion/execute@0
  displayName: Run GitVersion
  inputs:
    useConfigFile: true
    configFilePath: ${{ parameters.gitversion_config_path }}
    updateAssemblyInfo: true

This is the error I am getting. Note, it's an on-premise Azure DevOps installation, and most agents work, but some don't.

[daryltucker]

I was able to work around this:

1. Add Use .NET Core task before GitVersion task
2. Package to install: Runtime
3. Version: 2.1.0

GitVersion is also set up to use dotnet fullframework.

2.1.0 only show up for Runtime from what I can see:

curl https://dotnetcli.blob.core.windows.net/dotnet/release-metadata/2.1/releases.json -s | jq '.releases[]| .runtime.version'

Thankfully, only the Runtime seems to be needed :D
