Eclipse中Ant的配置与测试 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　然后在Builder面板中钩上Ant_Build 去掉Java Builder

　　再次编译即可在控制台看到Ant的输出

　　 Buildfile: F:\\eclipse projects\\Hello\\build xml init: pile: [mkdir] Created dir: F:\\eclipse projects\\Hello\\classes [javac] Compiling source files to F:\\eclipse projects\\Hello\\classes test: [mkdir] Created dir: F:\\eclipse projects\\Hello\\report [junit] Running example HelloTest [junit] Tests run: Failures: Errors: Time elapsed: sec pack: [mkdir] Created dir: F:\\eclipse projects\\Hello\\dist [jar] Building jar: F:\\eclipse projects\\Hello\\dist\\hello jar doc: [mkdir] Created dir: F:\\eclipse projects\\Hello\\doc [javadoc] Generating Javadoc [javadoc] Javadoc execution [javadoc] Loading source files for package example [javadoc] Constructing Javadoc information [javadoc] Standard Doclet version _ [javadoc] Building tree for all the packages and classes [javadoc] Building index for all the packages and classes [javadoc] Building index for all classes [javadoc] Generating F:\\eclipse projects\\Hello\\doc\\stylesheet css [javadoc] Note: Custom tags that could override future standard tags: @todo To avoid potential overrides use at least one period character ( ) in custom tag names [javadoc] Note: Custom tags that were not seen: @todo BUILD SUCCESSFUL Total time: seconds

　　Ant依次执行初始化编译测试打包生成API文档一系列任务极大地提高了开发效率将来开发J EE项目时还可加入部署等任务并且即使脱离了Eclipse环境只要正确安装了Ant 配置好环境变量ANT_HOME=<Ant解压目录> Path=…;%ANT_HOME%\\bin 在命令行提示符下切换到Hello目录简单地键入ant即可

在Eclipse中使用Ant Ant是Java平台下非常棒的批处理命令执行程序能非常方便地自动完成编译测试打包部署等等一系列任务大大提高开发效率如果你现在还没有开始使用Ant 那就要赶快开始学习使用使自己的开发水平上一个新台阶 Eclipse中已经集成了Ant 我们可以直接在Eclipse中运行Ant 以前面建立的Hello工程为例创建以下目录结构

　　新建一个build xml 放在工程根目录下 build xml定义了Ant要执行的批处理命令虽然Ant也可以使用其它文件名但是遵循标准能更使开发更规范同时易于与别人交流通常 src存放Java源文件 classes存放编译后的class文件 lib存放编译和运行用到的所有jar文件 web存放JSP等web文件 dist存放打包后的jar文件 doc存放API文档然后在根目录下创建build xml文件输入以下内容

　　 <?xml version= ?> <project name= Hello world default= doc > <! properies > <property name= src dir value= src /> <property name= report dir value= report /> <property name= classes dir value= classes /> <property name= lib dir value= lib /> <property name= dist dir value= dist /> <property name= doc dir value= doc /> <! 定义classpath > <path id= master classpath > <fileset file= $lib dir/* jar /> <pathelement path= $classes dir /> </path> <! 初始化任务 > <target name= init > </target> <! 编译 > <target name= pile depends= init description= pile the source files > <mkdir dir= $classes dir /> <javac srcdir= $src dir destdir= $classes dir target= > <classpath refid= master classpath /> </javac> </target> <! 测试 > <target name= test depends= pile description= run junit test > <mkdir dir= $report dir /> <junit printsummary= on haltonfailure= false failureproperty= tests failed showoutput= true > <classpath refid= master classpath /> <formatter type= plain /> <batchtest todir= $report dir > <fileset dir= $classes dir > <include name= **/*Test * /> </fileset> </batchtest> </junit> <fail if= tests failed > *********************************************************** **** One or more tests failed! Check the output **** *********************************************************** </fail> </target> <! 打包成jar > <target name= pack depends= test description= make jar file > <mkdir dir= $dist dir /> <jar destfile= $dist dir/hello jar basedir= $classes dir > <exclude name= **/*Test * /> <exclude name= **/Test* * /> </jar> </target> <! 输出api文档 > <target name= doc depends= pack description= create api doc > <mkdir dir= $doc dir /> <javadoc destdir= $doc dir author= true version= true use= true windowtitle= Test API > <packageset dir= $src dir defaultexcludes= yes > <include name= example/** /> </packageset> <doctitle><![CDATA[<h >Hello test</h >]]></doctitle> <bottom><![CDATA[<i>All Rights Reserved </i>]]></bottom> <tag name= todo scope= all description= To do: /> </javadoc> </target> </project>

　　选中Hello工程然后选择 Project Properties Builders New… 选择 Ant Build

　　填入Name Ant_Builder Buildfile build xml Base Directory $workspace_loc:/Hello（按 Browse Workspace 选择工程根目录）由于用到了junit jar包搜索Eclipse目录找到junit jar 把它复制到Hello/lib目录下并添加到Ant的Classpath中
