1.2.4. Building with Ant

We'll now build the tutorial with Ant. You will need to have Ant installed - get it from the Ant download page. How to install Ant will not be covered here. Please refer to the Ant manual. After you have installed Ant, we can start to create the buildfile. It will be called build.xml and placed directly in the development directory.
A basic build file looks like this:
<project name="hibernate-tutorial" default="compile">

    <property name="sourcedir" value="${basedir}/src"/>
    <property name="targetdir" value="${basedir}/bin"/>
    <property name="librarydir" value="${basedir}/lib"/>

    <path id="libraries">
        <fileset dir="${librarydir}">
            <include name="*.jar"/>
        </fileset>
    </path>

    <target name="clean">
        <delete dir="${targetdir}"/>
        <mkdir dir="${targetdir}"/>
    </target>

    <target name="compile" depends="clean, copy-resources">
      <javac srcdir="${sourcedir}"
             destdir="${targetdir}"
             classpathref="libraries"/>
    </target>

    <target name="copy-resources">
        <copy todir="${targetdir}">
            <fileset dir="${sourcedir}">
                <exclude name="**/*.java"/>
            </fileset>
        </copy>
    </target>

</project>
This will tell Ant to add all files in the lib directory ending with .jar to the classpath used for compilation. It will also copy all non-Java source files to the target directory, e.g. configuration and Hibernate mapping files. If you now run Ant, you should get this output:
C:\hibernateTutorial\>ant
Buildfile: build.xml

copy-resources:
     [copy] Copying 2 files to C:\hibernateTutorial\bin

compile:
    [javac] Compiling 1 source file to C:\hibernateTutorial\bin
