BuildXL/.azdo/common/set-variable-pats.yml

# Sets pipeline variables with appropriate PATs to use as environment variables in internal selfhost builds 
parameters:
- name: workingDirectory
  type: string
  default: $(Build.SourcesDirectory)
# This buildXLSourceDirectory parameter is introduced to handle the case when a pipeline checkouts multiple sources causing the PowerShell script file not found.
# When a pipeline checkouts a single source, then $(Build.SourcesDirectory) points to the local path on the agent where your source code files
# are downloaded, for example, c:\agent_work\1\s. However, if a pipeline checkouts multiple sources, for example, BuildXL.Internal and CloudBuild,
# then $(Build.SourcesDirectory) points to the parent directory of the checkout locations. For example, the BuildXL.Internal and CloudBuild repositories
# will be checked out, respectively, to c:\agent_work\1\s\BuildXL.Internal and to c:\agent_work\1\s\CloudBuild, while $(Build.SourcesDirectory) points
# $(Build.SourcesDirectory).

    # The filePath parameter is either an absolute path or a path relative to $(System.DefaultWorkingDirectory), which coincides
    # with $(Build.SourcesDirectory). If the filePath is only specified as a relative path r, then it points to $(Build.SourcesDirectory)/r.
    # However, if the pipeline checksout multiple sources (see above comment for buildXLSourceDirectory parameter), the file path will not exist.
