If I'm understanding you correctly, you expect the xml file to be maintained by hand. I think that using XML for this purpose is making it much too complicated. NAnt simply doesn't have a rich enough set of XML functions, and if you're going to
I need to deploy my application to various environments using a central build server. I have created sample xml that list the files/folders to be copied in each environment.
I want to call this XML file though NAnt and use Nant script
to run copy task based on the folders specific in xml. I am using server
aliases which are also defined in the same xml.
Has anyone tried this approach before…what is the best scripting approach for this type of requirement? I am
drop into C#, you may as well do it all in C# and skip the
NAnt, or else just have the C# generate a NAnt script.
But it's possible to do this in pure NAnt by using the features of the <foreach> task. Here's what I suggest you do:
1. Create a directory for environment description files. Create one file per environment Each file will be a NAnt project that defines the properties for that environment, e.g.
<project name="environment.dev" > <property name="AppServer" value="abcdev" /> <property name="WebServer" value="xyzdev" /> </project>
So far, so good.
2. Create a file that contains the mappings between source and destination files, and the machine, one per line, with a well-chosen separator. For example:
WindowsApp\AbcService\bin\release:AbcService\AppServer WebApp\AbcWeb:Inetpub\AbcWeb:WebServer
3. Loop over the environment files :
<foreach item="File" property="environment.file">
<in>
<items>
<include name="environments/*.environment" />
</item>
</in>
<do>
<call target="process-environment" />
</do>
</foreach>4. The process-environment target deals with exactly one environment file:
<target name="process-environment">
<include buildfile="${environment.file}" />
<call target="do-copy" />
</target>5. The do-copy target loops over the mapping file created in step 2:
<target name="do-copy">
<foreach item="Line" in="copy.commands" delim=":"
property="source,dest,server">
<do>
<copy file="${source}" tofile="\\${server}\${dest}" />
</do>
</foreach>
</target>Gary
