<project name="javac" default="compile" basedir=".">
    <property file="build.properties" />

    <property name="src" value="${basedir}"/>
    <property name="build.classes" value="${basedir}/build/classes"/>
    <property name="build.debug" value="off"/>
    <property name="build.optimize" value="off"/>

    <target name="prepare">
       <mkdir dir="${build.classes}" />
    </target>

    <target name="compile" depends="prepare">
       <javac srcdir="${src}"
              destdir="${build.classes}"
              debug="${build.debug}" optimize="${build.optimize}">
          <include name="${file}"/>
       </javac>
