修改jar包中文件

1、查看jar中文件

jar -tvf abc.jar

eg.

d:	mp	est20210619>jar -tvf asm-util-3.2.jar
   211 Tue Jul 07 00:05:20 CST 2009 META-INF/MANIFEST.MF

  3382 Tue Jul 07 00:05:22 CST 2009 org/objectweb/asm/util/TraceSignatureVisitor.class
   145 Tue Jul 07 00:05:22 CST 2009 org/objectweb/asm/util/Traceable.class

2、解压jar中文件

// 指定待解压的jar中目录，不指定默认解压整个jar包
jar -xvf abc.jar a/b/c

// 仅解压jar包中单个文件
jar -xvf strs-dist-hadoop-prod.jar logback.xml

3、更新jar中文件

// 更新指定目录下的所有文件
jar -uvf abc.jar a/b/c

//更新单个文件
jar -uvf strs-dist-hadoop-prod.jar logback.xml

文件夹a与abc.jar在同级目录
不指定文件夹a/b/c，默认当前目录为待更新的目标目录
覆盖更新指定目录的文件，原jar中不涉及的文件不做修改，亦不删除

例如：更新多个目录文件,(m表示包含MANIFEST.MF文件）

jar -uvf kafka_2.10-0.9.0.1.jar abc/* bb/*

4、创建jar包

// 将当前目录下所有文件打包
jar -cvf abc.jar ./*

创建jar包abc.jar，如果不存在，如果存在则覆盖
可以指定jar的存放路径，执行目录必须是需打包文件的根目录并且文件路径为相对路径

例如：指定多个目录打包，打好的jar包存放在根目录上一级目录

jar -cvf ./../abc.jar ./META-INF/* ./bb/* kk.log LICENSE NOTICE ./kafka/*
