添加的jar库文件到Ant构建

我加commons-codec.1.2.jar到我的Java构建路径添加的jar库文件到Ant构建

[javac] C:\Users\souzamor\workspace\tczip\src\tczip\Tczip.java:190: error: c 
annot find symbol 
    [javac] mdEnc = new String(Hex.encodeHex(diges 
t)); 
    [javac]      ^

这里是我build.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<project> 

    <target name="clean"> 
     <delete dir="build" /> 
    </target> 

    <target name="compile"> 
     <mkdir dir="build/classes" /> 
     <javac srcdir="src" destdir="build/classes" /> 
    </target> 

    <target name="jar"> 
     <mkdir dir="build/jar" /> 
     <jar destfile="build/jar/Tczip.jar" basedir="build/classes"> 
      <manifest> 
       <attribute name="Main-Class" value="tczip.ZipComparison" /> 
      </manifest> 
     </jar> 
    </target> 

    <target name="run"> 
     <java jar="build/jar/Tczip.jar" fork="true" /> 
    </target> 

</project>

我怎么能添加jar文件到build.xml文件？？我也有另外一个Java类称为Tczip哪些进程MD5：

[java] Processing: bhmcommonclient.zip 
[java] Exception in thread "main" java.lang.NoClassDefFoundError: org/apach 
mmons/codec/binary/Hex 
[java]  at tczip.Tczip.digest(Unknown Source) 
[java]  at tczip.Tczip.execute(Unknown Source) 
[java]  at tczip.ZipComparison.showFiles(Unknown Source) 
[java]  at tczip.ZipComparison.showFiles(Unknown Source) 
[java]  at tczip.ZipComparison.showFiles(Unknown Source) 
[java]  at tczip.ZipComparison.showFiles(Unknown Source) 
[java]  at tczip.ZipComparison.showFiles(Unknown Source) 
[java]  at tczip.ZipComparison.matchMD5(Unknown Source) 
[java]  at tczip.ZipComparison.main(Unknown Source)

我不认为我补充说，正确的到我的jar文件...我怎么能做到这一点？我完全新Ant

我将创建一个' jar'文件，这将是一个库文件...但编译我需要添加另一个'jar'到我的路径... – cybertextron

请参阅：http://stackoverflow.com/questions/722774/getting-ant-javac -to-recognized-a-classpath – davidmontoyago

首先这样声明它：

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

然后，你的javac元素中，包括在类路径是这样的：

<classpath> 
    <path refid="external.classpath" /> 
    </classpath>

同样的输出：'import org.apache.commons.codec.binary.Hex' – cybertextron

有一个错字，我是指1.1，现在我修好了。确保$ {lib.dir}将您引导至jar所在的正确位置。 –

dan我会更新我的问题...... – cybertextron
