Using replace token task for the file in the agent and resolving git bash path error

I have ensured git bash installed on the agent but still coming up with following error and i also added env variable

ERROR:

Unable to locate executable file: 'bash'. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.

I want to replace the token from that agent itself since that file will be available in the folder from the agent only, not in source code. and that file being generated from one of the task from azure pipeline.

that file content example:

https://dev-domain.com

here in above url, dev can be stage , prod etc , it need to be parameterized and use the replace token

  1. worked on installing git bash
  2. worked on adding the env variable path
  3. worked on replace token task but it is working if file is available in the source code, not if file is being generated in the agent directly.
Solution

  • Unable to locate executable file: 'bash'. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.

    I can reproduce the same issue when using the Windows Self-hosted agent.

    Based on your description, you have installed the git bash.

    To solve this issue, you can add bash command folder in the PATH of environment variable on the agent machine.

    Here are the steps:

    Step1: Check if the bash.exe exists in the git bin folder.

    For example:

    enter image description here

    Step2: You need to login the agent machine, and then add C:\Program Files\Git\bin to the Path of Environment Variables, then Restart the agent.

    Result:

    Update:

    To integrate all the steps into the Pipeline, you can add the following tasks:

    steps:

- task: PowerShell@2
  displayName: Install Git And Config PATH ENV
  inputs:
    targetType: 'inline'
    script: |
      # Define the URL of the Git installer
      $gitInstallerUrl = "https://github.com/git-for-windows/git/releases/download/v2.40.1.windows.1/Git-2.40.1-64-bit.exe"
      
      # Define the path to save the installer
      $installerPath = "$env:TEMP\Git-2.40.1-64-bit.exe"
      
      # Download the Git installer
      Invoke-WebRequest -Uri $gitInstallerUrl -OutFile $installerPath
      
      # Run the installer silently
      Start-Process -FilePath $installerPath -ArgumentList "/SILENT", "/NORESTART" -Wait
      
      # Optionally, remove the installer after installation
      Remove-Item -Path $installerPath
      $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User")
      echo $env:Path
      $gitpath = git --exec-path
      $bashpath = $gitpath.Replace('mingw64/libexec/git-core','bin')
      echo "##vso[task.setvariable variable=PATH]$bashpath;$(PATH)"


- task: Bash@3
  inputs:
    targetType: 'inline'
    script: |
      echo "test"

    Update2:

    To directly update the file on agent machine, you can use the Bash task to run the sed command to achieve it.

    Here is an example:

    variables:
  newvalue: dev01

steps:
- bash: 'sed -i -e "s/dev02/$(newvalue)/g" filename'
  workingDirectory: 'Local Path folder where the file located(e.g. C:\Users\xx\Downloads)'
  displayName: 'Bash Script'
