Display Java Error when Ant Build Fails

I am invoking a Java Class through ant script. Is there any way in which we can display the error message of the Invoked Java class in the Ant Build Fail message?

Thanks

With all due respect for the above answers. I think I got a simpler solution. While running the ant script, if we call the command with a -d option in the end, it displays a lot more information alongwith the failure reason for the java class also.

Hence, the command would be :

ant fileName.xml -d

Cheers!

Yes, it is possible.

<target name="test_java">
    <java classname="Test">
        <classpath>
            <pathelement path="${cpath}"/>
        </classpath>
    </java>
</target>

The Test class source code:

public class Test {

public static void main(String[] args) {
    int a = 2;

    System.out.println(String.valueOf(a/0));
}

}

The output:

test_java:
Exception in thread "main" java.lang.ArithmeticException: / by zero
at Test.main(Test.java:7) Java
Result: 1

I assume you are using the task to do this? If so, you can redirect stderr to a property with the errorproperty attribute, and then include that property in your message in the task. You would have to have failonerror="false" and have some other method of detecting the error (a based on the process status code perhaps).
