Java project Ant build error

Question

Hi I'm trying to use ant to package my project. I'm unfamilar with it's details and have run into trouble during build.

My project directory structure is shown below:

project directory

When I run the ant script I get the following error:

 Buildfile: C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\build.xml

 BUILD FAILED
 C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\build.xml:12:      
 Cannot find C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\nbproject\build-impl.xml 
 imported from C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\build.xml

The build.xml file contains these lines at the start:

 <project name="QuizServer" default="default" basedir=".">
<description>Builds, tests, and runs the project QuizServer.</description>
<import file="nbproject/build-impl.xml"/>

The warp.xml file contains the following:

 <project name="quizserver" basedir="." default="main">

<property name="src.dir"     value="src"/>
<property name="build.dir"   value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="jar.dir"     value="${build.dir}/jar"/>
<property name="main-class"  value="quizserver.QuizServer"/>
<property name="lib.dir"     value="libs"/>

<path id="classpath">
    <fileset dir="${lib.dir}" includes="**/*.jar"/>
</path>


<target name="clean">
    <delete dir="${build.dir}"/>
</target>

<target name="compile">
    <mkdir dir="${classes.dir}"/>
    <javac srcdir="${src.dir}" includeantruntime = "false" source = "1.7" target = "1.7" fork="true" destdir="${classes.dir}" classpathref="classpath" compiler="classic" />
</target>

<target name="jar" depends="compile">
    <mkdir dir="${jar.dir}"/>
    <jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
        <manifest>
            <attribute name="Main-Class" value="${main-class}"/>
        </manifest>
    </jar>
</target>

<target name="run" depends="jar">
    <java fork="true" classname="${main-class}">
        <classpath>
            <path refid="classpath"/>
            <path location="${jar.dir}/${ant.project.name}.jar"/>
        </classpath>
        <jvmarg value="-Xmx512m"/>
        <jvmarg value="-Xmx512m"/>
    </java>
</target>

<target name="clean-build" depends="clean,jar"/>

<target name="main" depends="clean,run"/>

I've searched to no avail, it's probablly obvious and if so please could you kindly point out what the problem may be?

Update: I've added a build-impl.xml file from a same named NetBeans project to the directory. Now when I run the build.xml file I am getting the following error:

 Buildfile: C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\build.xml
 -pre-init:
 -init-private:
 -init-user:
 -init-project:
 -init-macrodef-property:
 -do-init:
 -post-init:
 -init-check:

 BUILD FAILED
 C:\Users\Trip Admin\Documents\Eclipse Projects\QuizServer\build-impl.xml:226: Must set src.dir

Build-impl.xml file line 225 and 226 are below:

 <target depends="-pre-init,-init-private,-init-user,-init-project,-do-init" name="-init-check">
    <fail unless="src.dir">Must set src.dir</fail>

Many thanks

The error is very clear, Ant cannot find this file:

nbproject/build-impl.xml

That folder is not in your directory structure.
