Unable to locate executable file: 'bash" error : Inline script using Bash@3 Azure DevOps task

Question

I was getting below error on using a self hosted windows agent.

##[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.

Here is my pipeline - Goal of task was to get the filename alone from the whole filePath and to use this filename in further tasks.

trigger:
 - master

parameters:
 project: './test/abc/UnitTest.proj'

pool: self-hosted-windows

steps:
 - task: Bash@3
   inputs:
     targetType: 'inline'
     script: |
       input="${Parameters.project}"
       file_name_with_ext="${input##*/}"
       file_only="${file_name%.*}"
       echo "File : $file_only"

Answer 1

The issue is you didn't add bash command folder in the PATH of environment variable on the agent machine.

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 service.
