[nant-dev] recursive includes

[Gert Driesen]

Hi,   I want to create a hierarchy of included configuration files, where each level of the hierarchy adds information.   eg.  I want to have the following directory structure :       examples         mono             1.0                 Tutorials                     WebApp   in each directory I would want to have both a build file and a config file.   The buildfile in each directory would do an include of the config file in the same directory.   And the config file in each directory would do an include of the config file in the parent directory and add specific configuration information on it's level.   For example :   in the examples\mono\1.0 directory, the nant.config would contain :    <!-- Include parent configuration file -->  <include buildfile="../nant.config" failonerror="true" />  <!-- Set runtime version -->  <property name="project.runtime.version" value="1.0" readonly="false" /> in the examples\mono directory, the nant.config would contain :    <!-- Include parent configuration file -->  <include buildfile="../nant.config" failonerror="true" />  <!-- Set runtime configuration -->  <property name="project.runtime.config" value="mono" readonly="false" />   so for the buildfile in the examples\mono\1.0 directory, the following properties would be available :    <property name="project.runtime.version" value="1.0" readonly="false" />  <property name="project.runtime.config" value="mono" readonly="false" /> and if I was to decide that the project.runtime.config for all examples in the examples\mono directory should be mono-something, then I would only have to change the nant.config file in the examples\mono directory, and all underlying buildfiles would automatically get the updated property value.   So what I want is to be able to have each level manage only it's own configuration properties, but Nant currently does not allow recursive includes.  Right now, I get the following exception :   [NAnt.Task:include Generated Exception  - [] <>] Exception: SourceForge.NAnt.BuildException Message: D:\CVS\log4net\examples\mono\nant.config(4,3):  Recursive includes are not allowed.

Try 'nant -help' for more information   I never have circular references so I don't see why this shouldn't be possible.   Can anyone comment on this ?   Thanks,   Gert
