Run ant scripts using ProcessBuilder

[prsindagi]

This is what I have done so far:


import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;


public class BuildClass {


public BuildClass() {
}
public static void main (String args[]) throws Exception{


String s = null;
ProcessBuilder pb = new ProcessBuilder();


Map<String,String> env = pb.environment();
String path=null;
if(env.containsKey("Path")){
path=env.get("Path");

}

path=path+";C:\\ANT 1.7.0\\bin\\;";
env.put("JAVA_HOME","C:\\Program Files\\Java\\jdk1.5.0_10");
env.put("Path",path);

pb.redirectErrorStream(true);
pb.directory(new File("C:/xyz/pqr/uvw/"));


pb.command("ant","jar");
Process p = pb.start();
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((s = stdInput.readLine()) != null) {

System.out.println(s);
}

}
}



----------------
When i run this i get:
Exception in thread "main" java.io.IOException: CreateProcess: ant jar error=2
at java.lang.ProcessImpl.create(Native Method)
at java.lang.ProcessImpl.<init>(ProcessImpl.java:81)
at java.lang.ProcessImpl.start(ProcessImpl.java:30)
at java.lang.ProcessBuilder.start(ProcessBuilder.java :451)
at BuildClass.main(BuildClass.java:51)
Java Result: 1


But if I change pb.command("ant","jar"); to pb.command("notepad");
Its working fine.

Could anyone help

Can you check if ant.bat is in PATH variable?
you may also want to try ant.bat instead of only ant.

I have already put the ant in the path :

path=path+";C:\\ANT 1.7.0\\bin\\;";

[priyanka.dandekar]

try C:\\ANT 1.7.0\\bin\\ant instead of just ant

and see if it gives same error?

I am able to run this using this line

pb.command("ant.bat", "jar");

its related to the name of the file then....

If you see the code I have set the path:

Map<String,String> env = pb.environment();
String path=null;
if(env.containsKey("Path")){
path=env.get("Path");

}

path=path+";C:\\ANT 1.7.0\\bin\\;";
env.put("JAVA_HOME","C:\\Program Files\\Java\\jdk1.5.0_10");
env.put("Path",path);


----------

pb.command("C:\\ANT 1.7.0\\bin\\ant.bat","jar"); --- Only this works

pb.command("C:\\ANT 1.7.0\\bin\\ant","jar"); --- Even this does not work

pb.command("ant","jar"); --- this won't work
pb.command("ant.bat","jar"); --- this won't work


Need to know why?You have any idea
