nAnt script needs to get parent directory

Question

I am writing a nAnt script and need to get the parent directory. I have used:

<property name="perforceWS" value="${project::get-base-directory()}"/>

this returns the current directory. How can I get the property to be the parent's directory?

Answer 1

Assuming You mean the parent directory of the project directory (the directory where the NAnt build script is located) this is the answer:

<property
  name="perforceWS"
  value="${directory::get-parent-directory(project::get-base-directory())}"/>
