蚂蚁java lang class没有发现异常

Question

我对Ant很新，但是我有一个大体的了解。我只是无法得到这个工作。

<?xml version="1.0"?> 
<project name="Ser321 Assignment 3 Java Movie Library with Ant build file and API support." 
     default="targets" basedir="." 
     xmlns:dn="antlib:org.apache.ant.dotnet" 
     xmlns="antlib:org.apache.tools.ant"

    <target name="targets">

    </path> 
    <path id="external.classpath"> 
     <pathelement location="${lib.dir}/json.jar"/> 
    </path> 

    <target name="prepare"> 
     <mkdir dir="${build}" /> 
     <mkdir dir="${bin}"/> 
     <mkdir dir="${obj}"/> 
    </target> 

    <target name="clean"> 
     <delete dir="${build}" failonerror="false"/> 
     <delete dir="${bin}" failonerror="false"/> 
     <delete dir="${obj}" failonerror="false"/> 
    </target> 

    <target name="build" depends="prepare"> 
     <javac srcdir="${src.dir}" 
      includeantruntime="false" 
      destdir="${build}"> 
     <classpath refid="external.classpath"/> 
     </javac> 
    </target> 

    <target name="execute.jar" depends="build" 
      description="Run the program"> 
     <java classname="Main" fork="yes"> 
      <classpath refid="compile.classpath"/> 
     </java> 
    </target> 

</project> 

这给我我的课程文件夹与电影作为下一个文件夹，然后在那里，我有我的3班。然而，它一直说不上课，我不知道我做错了什么。

想通了。我有时候是个空头人。

<target name="execute.jar" depends="build" 
     description="Run the program"> 
    <java classname="movie.Main" fork="yes"> //added movie.main instead of Main 
     <classpath refid="compile.classpath"/> 
    </java>
