There are two ways you can go about doing this:
- Use a path that is consistent on all machines. This could be a UNC (Windows) or Full network path (Linux)
- Use a relative path to {PROJECT_ROOT}. If you are using "deploytool -package projectFile.prj" then in the project file you can use {PROJECT_ROOT}\..\..\path\to\desired\directory
Please note that System environment variables are not available to be used in the paths.
