Bamboo variable resolve to empty string in powershell script

I've got a powershell script within a git repository that I use to build the project.

In the script, I'm trying to run the following command

Get-ChildItem -Path ${bamboo.build.working.directory}\src -Filter project.json -Recurse | ForEach-Object { & dnu restore $_.FullName 2>1 }

and the above returns the following error

11-Feb-2016 12:39:43Get-ChildItem : Access to the path 'C:\cygwin\home\Administrator\.ssh' is denied.
11-Feb-2016 12:39:43At C:\build\FCL-FCRP-JOB1\Build\01_Build.ps1:26 char:1
11-Feb-2016 12:39:43+ Get-ChildItem -Path ${bamboo.build.working.directory}\src -Filter project.json - ...

The above script would run fine as INLINE, but the variable would resolve to empty string if it ran as a File.

Does anyone experience the same problem? Or am I missing something here?

Thank you.

Bamboo can indeed only expand variables when you use an inline script.
When you use a script file, PowerShell has absolutely no knowledge what those ${bamboo...} things are.

Passing them as arguments, or use the Bamboo environment variables, will do the trick.

To answer my own question, it turns out if you use powershell script inline, bamboo automatically substitute the bamboo variable into their respective values. However if you run it as a file, then you need to pass in the bamboo variable as arguments, so you need a param block inside the script file.
