错误：无法添加源文件：-p不存在

Question

我正在尝试使用勺子进行流程注释。我按照示例（http://spoon.gforge.inria.fr/Doc/Basic#toc3）使用Ant运行勺子（因为勺子不适用于当前版本的Eclipse。

<?xml version="1.0"?>
<project name="TestBound" default="main" basedir=".">
    <!-- Sets variables which can later be used. -->
    <property name="src.dir" value="src" />
    <property name="build.dir" value="bin" />
    <property name="dist.dir" value="dist" />
    <property name="extlib.dir" value ="D:\Java_Lib\Libs" />


    <path id="build.classpath">
        <pathelement location="${extlib.dir}\spoon-core-1.5-jar-with-dependencies.jar" />
        <pathelement location="${extlib.dir}\SpoonTest.jar" />
    </path>
        <!-- define spoon task -->

    <taskdef name="spoon" classname="spoon.SpoonTask" classpathref= "build.classpath"/>


    <!-- Deletes the existing build, docs and dist directory-->
    <target name="clean" description="Deletes the existing build, docs and dist directory" >
        <delete dir="${build.dir}" />
        <delete dir="${dist.dir}" />
    </target>

    <!-- Creates the  build, docs and dist directory-->
    <target name="makedir" description="Creates the  build, docs and dist directory">
        <mkdir dir="${build.dir}" />
        <mkdir dir="${dist.dir}" />
    </target>

        <!-- Creates the  build, docs and dist directory-->
    <target name="modify" description="modify the source code" >

        <spoon classpathref="build.classpath" verbose="true">
            <sourceSet dir= "${src.dir}" includes= "*.java" />
            <processor type= "com.richardle.Bound2Processor" />
        </spoon>

    </target>

    <!-- Compile Java code -->
    <target name="compile" description="Compile Java code" depends="clean, makedir, modify">
        <javac destdir="${build.dir}" srcdir="${src.dir}" includeantruntime ="false">
            <classpath refid="build.classpath" />
        </javac>
    </target>

    <!--

            <manifest>
                <attribute name="Main-Class" value="com.richardle.testgson.TestGson"/>
            </manifest>
        </jar>
    </target>
    -->
    <target name="main" depends="compile">
        <description>Main target</description>
    </target>
</project>

虽然，我把处理器的编译jar文件和独立勺子jar文件放在classpath中，但是在用Ant编译时仍然会出错

我的工作有问题吗？我必须使用勺子（或一些相关的处理器），我不能使用Java Annotation Processor，因为它无法修改输入源代码，它只是生成新文件。
