Subject RE: Dynamically increase the number of arguments to EXEC task based on the number and name of the file(s) in a directory.

Hi Mohan,

I don't know if this will solve your immediate problem, but when I need
dynamic behavior in a build I use an xslt stylesheet and an xml file to
create my build script.  I see ANT as just a processor and the build file as
just data.  So I try to generate the data for the build in advance and in
this way get seemingly "dynamically."  There are probably other less radical
solutions to your issue, but I thought you might be interested in an
approach that's worked really well for me.

All the best,

Brian

Subject: Dynamically increase the number of arguments to EXEC task based on
the number and name of the file(s) in a directory.

Hello All,

 

Requirement: Dynamically increase the number of arguments to EXEC task
based on the number and name of the file in a directory.

 

For example a sample directory contains the following files with
extension "*.rod" (Number of rod files in the "src" directory
dynamically change): 

C:\src> dir /b *.rod

Details.rod

Info.rod

Summary.rod

 

Right now, I'm hard coding the file names in arguments to EXEC task in
the following way

<target name="erdpro">

            <condition property="erdpro.client.dir" value="C:\Program
Files\Actuate8\eRDPro\bin" >

              <os family="windows"/>

            </condition>       

 

            <echo> Compiling ROD files. Please wait...</echo>

            <exec dir="${erdpro.client.dir}"
executable="${erdpro.client.dir}/erdpro" >

                        <arg value="-b"/>

                        <arg value=" Details.rod" />

                        <arg value=" Info.rod" />

                        <arg value=" Summary.rod" />

            </exec>

</target>

 

Above target is good when I hardcode the files to the "arg". I want to
dynamically add "arg" values based on the number and name of the file. I
want to know how I can achieve my requirement. (Should I use marcodef?
If so how?)

 

Any help is highly appreciated.

 

Thanks,

Mohan
