Eclipse External Tool Variables

Question

I have a project called at_extended in my eclipse:

C:\Users\joanet\git\TD_RF_Module_SDK\examples\core\at_extended

which includes this file

C:\Users\joanet\git\TD_RF_Module_SDK\examples\core\at_extended\TD1204 Release\at_extended.bin

and these arguments to execute an external tool

-f "${git_work_tree:${project_name}}/bin/${project_name}/${config_name:${project_name}}/${project_name}.bin" –r

But when I run Tools, choosing a project, I got this error:

Could not open file: C:\Users\joanet\git\TD_RF_Module_SDK/bin/at_extended/TD1204 Release/at_extended.bin.
