Eclipse下用ant打包时怎么添加jar包

Eclipse下用ant打包时如何添加jar包

方法一:

1) 右键点击打包所用的文件(build.xxx.xml),选择Run As à 3.Ant Build…

2) 进入编辑配置页面如图1-1:选择classpath, Add External JARs…

3) 添加所需jar包即可

方法二:

将jar包拷贝到jdk\jre\lib\ext目录下.例如:如果需要servlet-api.jar,jsp-api.jar(这两个jar包在tomcat的lib目录中存在),那么可以进行如下 *** 作

将tomcat\common\lib\servlet-api.jar拷贝到jdk\jre\lib\ext目录下

将tomcat\common\lib\jsp-api.jar拷贝到jdk\jre\lib\ext目录下(jsp自定义标签库需要)

注意:

该方法导入servlet-api.jar以后对项目在Eclipse中的运行没有影响

导入jsp-api.jar以后,可以正常打包,但是在Eclipse中运行项目会报错.打完包以后将jdk\jre\lib\ext目录下的jsp-api.jar删掉,项目即可正常运行.

个人推荐用方法一

你说的是ant的构建文件build.xml吗? 如果是 只要在jar标签中添加

<zipgroupfileset dir="${lib.dir}" includes="*.jar" />

例如：

<jar destfile=xxx >

<zipgroupfileset dir="${lib.dir}" includes="*.jar" /> //意思就是添加lib下所有的jar包

</jar>

抄一个例子给你,自己去领会吧。

build.properties:

classpath.external=C\:\\ExadelStudio\\lib\\servlet\\2.3\\servlet.jar

build.xml:

<project name= "empty " basedir= "../ " default= "build ">

<!-- Local system paths -->

<property file= "${basedir}/ant/build.properties "/>

<!--property name= "deploy.dir " value= "${exadel.home}/tomcat/webapps "/-->

<property name= "webroot.dir " value= "${basedir}/WebContent "/>

<property name= "webinf.dir " value= "${webroot.dir}/WEB-INF "/>

<property name= "build.dir " value= "build "/>

<!-- Project settings -->

<property name= "project.distname " value= "empty "/>

<!-- classpath for Struts 1.1 -->

<path id= "compile.classpath ">

<pathelement path = "${webinf.dir}/lib/commons-beanutils.jar "/>

<pathelement path = "${webinf.dir}/lib/commons-digester.jar "/>

<pathelement path = "${webinf.dir}/lib/struts.jar "/>

<pathelement path = "${webinf.dir}/classes "/>

<pathelement path = "${classpath.external} "/>

<pathelement path = "${classpath} "/>

</path>

<!-- Check timestamp on files -->

<target name= "prepare ">

<tstamp/>

</target>

<!-- Copy any resource or configuration files -->

<target name= "resources ">

<copy todir= "${webinf.dir}/classes " includeEmptyDirs= "no ">

<fileset dir= "JavaSource ">

<patternset>

<include name= "**/*.conf "/>

<include name= "**/*.properties "/>

<include name= "**/*.xml "/>

</patternset>

</fileset>

</copy>

</target>

<!-- Normal build of application -->

<target name= "compile " depends= "prepare,resources ">

<javac srcdir= "JavaSource " destdir= "${webinf.dir}/classes ">

<classpath refid= "compile.classpath "/>

</javac>

</target>

<!-- Remove classes directory for clean build -->

<target name= "clean "

description= "Prepare for clean build ">

<delete dir= "${webinf.dir}/classes "/>

<mkdir dir= "${webinf.dir}/classes "/>

</target>

<!-- Build entire project -->

<target name= "build " depends= "prepare,compile "/>

<target name= "rebuild " depends= "clean,prepare,compile "/>

</project>
