ParserError during PowerShell script execution - Bug or design?

Hmm, I'm not sure if it's about escaping method, afaik groovy has the same single and double quote syntax as PowerShell or many other languages. I think it's more that groovy can import internal/collector functions like hostProps.get() without the collector needing to directly modifying your code with search-replace. Since the collector is java-based I assume that was easy to do but powershell is dotnet based so it can't just import java classes.
