Ant将多个jar打包为一个jar

推荐使用 ：（来自官方文档）

http://ant.apache.org/manual/

使用 restrict  archives

<jar destfile= "${lib.dir}/${project.name}-${version}.jar" basedir="${classes.dir}" >

                                                 <restrict>

                                                                 <name name= "**/*.class" />

                                                                 <archives>

                                                                                 <zips>

                                                                                                 <fileset refid= "log4j-1.2.15.jar" />

                                                                                                 <fileset refid= "commons-codec-1.4.jar" />

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

                                                                                                 <fileset dir= "${env.YOYO_SVN_HOME}" includes="app/java/testng/6.8/testng-6.8.jar" />

                                                                                 </zips>

                                                                 </archives>

                                                 </restrict>

                                                 <manifest>

                                                                 <attribute name= "Main-Class" value="com.yoyosys.woyun.CompareFileMd5OrLength" />

                                                 </manifest>

                                 </jar>

 

  

 

   <jar destfile="${lib.dir}/${project.name}-${version}.jar" basedir="${classes.dir}">

               这里可以添加 制定的jar 包，但是，制定的jar包 不会在 classpath中使用，所哟要使用  

manifest 的 Class-Path 属性 ，将 jar包的内 打进的jar包 ，路径指定了 ， 

 

               <manifest>
                    <attribute name="Class-Path" value="${mf.classpath}" />
                    <attribute name="Main-Class" value="com.yoyosys.woyun.CompareFileMd5OrLength"/>
               </manifest>
          </jar>

 

  1 Manifest-Version: 1.0
  2 Ant-Version: Apache Ant 1.8.2
  3 Created-By: 1.6.0_31-b04 (Sun Microsystems Inc.)
  4 Main-Class: com.yoyosys.woyun.CompareFileMd5OrLength
  5 Class-Path: log4j-1.2.15.jar commons-codec-1.4.jar

 

将打好的jar包 解压 可以看到  在 ：META-INF/MANIFEST.MF 信息中可以看到  表明  在 打好的jar保重 包含 了 

 

log4j-1.2.15.jar commons-codec-1.4.jar  这两个jar 包
