ant not executing .exe file - ant

Question

my searchversion.exe file is not running in the script..why is that so?
<project name="nightly_build" default="main" basedir="checkout">
<target name="init">
<property file="initial.properties"/>
<property file="C:/Work/lastestbuild.properties"/>
<tstamp>
<format property="suffix" pattern="yyyyMMddHHmmss"/>
</tstamp>
</target>
<target name="main" depends="init">
<sequential>
<exec executable="C:/Work/Searchversion.exe"/>
...
</sequential>
</target>
</project>
Searchversion.exe will generate latestbuild.properties file. I do not have any arguments for Searchversion.exe.
Here is the code for searchversion.exe:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace Search
{
class Program
{
static void Main(string[] args)
{
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.FileName = "sslist.exe";
p.StartInfo.Arguments = "-R -H -h sinsscm01.ds.net /mobile";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.Start();
string procOutput = p.StandardOutput.ReadToEnd();
string procError = p.StandardError.ReadToEnd();
TextWriter outputlog = new StreamWriter("C:\\Work\\listofsnapshot.txt");
outputlog.Write(procOutput);
outputlog.Close();
string greatestVersionNumber = "";
using (StreamReader sr = new StreamReader("C:\\Work\\listofsnapshot.txt"))
{
while (sr.Peek() >= 0)
{
var line = sr.ReadLine();
var versionNumber = line.Replace(#"6.70_Extensions/6.70.102/ANT_SASE_RELEASE_", "");
if(versionNumber.Length != line.Length)
greatestVersionNumber = versionNumber;
}
}
Console.WriteLine(greatestVersionNumber);
TextWriter latest = new StreamWriter("C:\\Work\\latestbuild.properties");
latest.Write("Version_Number=" + greatestVersionNumber);
latest.Close();
}
}
}
sslist.exe gets a list of snapshots found in my version control software, and i will get the greatest version number and save it as a text (latestbuild.properties)

Answer 1

Two things in your script look odd.
I don't think you need the <sequential> task in the <main> target.
The depends attribute of you <main> target will cause the <init> target to run before Searchversion.exe. So, perhaps it is getting run, just too late.
Assuming #2 is the cause of your problem you should restructure your script to look like this:
<project name="nightly_build" default="main" basedir="checkout">
<target name="init">
<exec executable="C:/Work/Searchversion.exe"/>
<property file="initial.properties"/>
<property file="C:/Work/lastestbuild.properties"/>
<tstamp>
<format property="suffix" pattern="yyyyMMddHHmmss"/>
</tstamp>
</target>
<target name="main" depends="init">
...
</target>
</project>
