问题 I would like to unjar multiple JAR files and then rebuild into one JAR using an ant build script. Is this possible? 回答1: Yes, it's possible with ant. A jar file is basically a zip with a special manifest file. So to unjar, we need to unzip the jars. Ant includes an unzip task. To unzip/unjar all the jar files in your project: <target name="unjar_dependencies" depends="clean"> <unzip dest="${build.dir}"> <fileset dir="${lib.dir}"> <include name="**/*.jar" /> </fileset> </unzip> </target>
