[NAnt-users] CCnet progress reporting from NAnt

[Mike Frederick]

I have implemented a custom script task for NAnt which makes progress 
reporting back to CCNet much easier.  Progress reporting is accomplished 
by inserting XML into a file which is read by CCNet to display progress 
information.  See 
http://confluence.public.thoughtworks.org/display/CCNETCOMM/Viewing+build+progress+with+Nant+and+MSBuild
 
for official details.

I am attaching the script for anyone to use.  What I do is:

1) save the contents of the script below in a file named CCNet-progress.xml
2) include the new file in any NAnt script which will want to utilize it 
like:

    <include buildfile="CCnet-progress.xml"/>

3) call the progress reporter when you want to update the progress of 
your task, like this:

    <CCnet-progress message="Beginning the web site clean-up" 
file="${CCNetListenerFile}"/>

and that's it.  I usually do a little more, like set a true/false 
variable like this:

    <property name="progress.logging" value="false"/>
    <property name="progress.logging" value="true" 
if="${property::exists('CCNetListenerFile')}"/>

and then my actual progress logging calls look like:

    <CCnet-progress message="Beginning the web site clean-up" 
file="${CCNetListenerFile}" if="${progress.logging}"/>

This allows my NAnt scripts to continue working when I am using them 
outside of CCNet.

Here's the file:
