using foreach to loop through strings

Hi,

 

I’m trying to make my build scripts a bit more maintainable.  Part of the build script’s job is to tag code into svn and export code from svn.  We have a directory in svn called ‘thirdParty’ to hold our thirdParty libs.    The thirdParty directory holds thirdParty libs for many different applications.

 

In my application build script, I am currently itemizing each individual thirdParty folder in both the target that tags the source code and the target that exports the source code.  If I add a new thirdParty dependency, I have to remember to update the build script in both places. 

 

What I’d like to do is keep a “list” of thirdParty dependencies by my application in a single place.  Then in both the tag and export targets iterate over that list and build the appropriate command from the items in that list.  I’m trying to use fileset and foreach tasks to accomplish this, but so far I haven’t been able to get it to work.

 

My fileset looks like (this is not contained in a target):

  <fileset id="thirdPartyDirs" >

    <include name="LLBLGenPro_v2.6" asis="true" />

    <include name="AjaxControlToolkit" asis="true" />

  </fileset>

 

And here’s a portion of my target for exporting using the foreach task:

<target name="export.source.new" description="Gets the latest files from Svn">

 

    <foreach item="String" property="thirdParty.name" >

      <in>

        <items refid="thirdPartyDirs" />

      </in>

      <do>

        <echo message="found ${thirdParty.name}"/>

       

        <exec program="svn">

          <arg value="export" />

          <arg value="--force" />

          <arg value="${export.source.root}/thirdParty/${thirdParty.name}" />

          <arg value="${buildarea.application.thirdparty}/${thirdParty.name}" />

        </exec>

      </do>

    </foreach>

…

 

Something is not set up quite right as the message "found ${thirdParty.name}" never gets printed.

 

What am I missing?  Or, if there is a easier/better way to accomplish the same thing using different tasks, please let me know.

I am using the latest nightly build: (Build 0.86.3412.0; nightly; 5/5/2009)

 

Thanks,

Beth

Your fileset it probably empty. You don't specify a basedir. Is AjaxControlToolkit literally the name of a file?

Beth,

 

To iterate a FileSet, I think you will need to set the item in the <foreach> task to File rather than String e.g.

 

    <foreach item=”File” property=”thirdPatry.name”>

       <in>

           <items refid=”thridPartyDirs” />

            Etc.

 

Also. if you want to check if the FileSet contains files, you can use the fileset::to-string in NAntContrib.  E.g.

 

    <echo message="${fileset::to-string('thirdPartyDirs', ' | ')}">

 

will write a pipe delimited list of the files to the log/console

 

HTH,

Bill
