Maven Ant Tasks - Dependencies

Question

I am trying to set the ant build file to user Maven dependencies and I am getting error as "Failed to create task or type urn:maven-artifact-ant:localRepository

 package uk.co.rrv;

import org.joda.time.DateTime;

public class Main {
    public static void main(String[] args) {
        DateTime dateTime = new DateTime();
        System.out.println("DateTime = " + dateTime);


        System.out.println("Plus 1 hour is " + dateTime.plusHours(1));
        System.out.println("Plus 10 minutes is " + dateTime.plusMinutes(10));
        System.out.println("Plus 60 seconds is " + dateTime.plusSeconds(60));

    }
}

Here is my Build xml file

Answer 1

After fixing the references to maven-ant-tasks jar,

-    <path id="maven-ant-tasks.classpath" path="Lib/maven-ant-tasks-2.1.3.jar" />
+    <path id="maven-ant-tasks.classpath" path="lib/maven-ant-tasks-2.1.3.jar" />

-        <javac ... classpathref="maven-ant-tasks.classpath"/>
+        <javac ... classpathref="compile.classpath"/>

-                <path refid="classpath"/>
+                <path refid="runtime.classpath"/>

-                 classpath="Lib/maven-ant-tasks-2.1.3   .jar"/>
+                 classpath="lib/maven-ant-tasks-2.1.3.jar"/>

See also usage examples in the docs including bootstrapping via ant that probably has useful examples.
