我是全新的Ant，我不知道如何classpath在Ant. 我写了一个Java类来为我编写一些脚本，我想将它部署为一个taskin Ant. 该类commons-codec-1.2.jar用作外部库，在其他方面为我做一些Unicode和MD5任务。我已经发布了我的build.xml文件。

<?xml version="1.0" encoding="ISO-8859-1"?>
    <project name="TcZip" basedir="." default="jar">

    <property name="src.dir" value="src" />
    <property name="classes.dir" value="classes" />
    <property name="library.dir" value="library" />

    <path id="external.classpath">
        <pathelement location="${library.dir}/commons-codec-1.2.jar" />
    </path>

    <target name="clean" description="Delete all generated files">
    <delete dir="classes" />
    <delete file="TcZip.jar" />
    </target>

    <target name="compile" description="Compiles the task">
    <mkdir dir="${classes.dir}" />
    <javac srcdir="src" destdir="classes" />
        <classpath>
            <path refid="external.classpath" />
        </classpath>
    </target>

    <target name="jar" description="JARs the Task" depends="compile">
    <jar destfile="TcZip.jar" basedir="classes" />
    </target>

    <target name="use" description="Use the task" depends="jar">
    <taskdef name="tczip" classname="ZipComparision" classpath="${ant.project.name}.jar" />
    <tczip />
    </target>

</project>

在我的task目录中，我有：

+task
 - build.xml
 - classes
 - library
 - src

library并classes包含该commons-codec-1.2.jar文件。但是，如build.xml文件中所示，我<property>为library. 当我执行时，ant compile我得到：

compile:
    [javac] C:\workspace\task\build.xml:19: warning: 'includeantr
untime' was not set, defaulting to build.sysclasspath=last; set to false for rep

    [javac]   symbol:   variable Hex
    [javac]   location: class Tczip
    [javac] 3 errors

BUILD FAILED
C:\workspace\task\build.xml:19: Compile failed; see the compiler
error output for details.

有人可以帮我吗？谢谢

将指令替换location为.pathelementpath
