Jar反编译逆向2.0教程实战

小杨今天带了逆向2.0的课程实战：

jar逆向1.0课程

1.0和2.0课程实战的区别在哪里？1.0从零反编译，需要懂一点java，2.0非技术人员，不懂代码也能完成对代码的反编译。

统计命令：dir /b /s *.java | find /c ".java"

修复率 = 500 ÷ 537 × 100% = 93.1%

剩余报错占比 = 387 ÷ 25,729 × 100% = 1.50%

2.0实战不需要懂代码，可直接执行工具逆向修复报错生成源码。

jdk环境和maven环境

Maven环境本地配置脚本

Mvn本地脚本打包命令：解压jar包里面的依赖lib放到本地文件目录然后编写批量处理脚本可以执行mian方式，这里写的javademo，如果通过工具下载的会自动生成install和pom文件

项目补第三方依赖包打包到本地：这步操作很关键

找到源码jar解压一下文件：

把lib复制到非中文目录：比如d盘的lib:

替换打包本地lib的路径我脚本自动给你生成好：

替换本地路径lib，脚本lib我都给你生成好了

使用本地cmd打入环境：

上面的包是根据你项目的lib来我这里只是参考

等包执行跑完不要着急：

本地依赖我们打好了，能打依赖记得要配置maven环境：配置系统环境变量就行，版本没有影响。

Idea配置jdk和maven环境

项目需要配置jdk的位置：

这几个都要点一下设置一下：

这里的jdk根据你项目实际情况修改，如果是17改成17，如果是21改成21

设置编译的jdk也需要改版本：

配置maven环境本地仓库

本地pom包的引用过来：

检查项目编译报错总数

项目报错是根据项目实际情况个数来的我这个换了一个项目有7个报错，视频是300多个报错，我们换个项目

这个项目347个报错这个时候后面只需要用ai工具修复就行了。

ai工具安装使用和修复

使用cursor代码修复：

Cursor下载安装就行：

https://cursor.com/cn/download

cursor 工具自己买账号（账号）我用pro账号180一个月，也有token算量工具，如果需要可以联系楼主

使用cursor完整代码修复：

复制项目报错多开cursor窗口续费报错，操作修复就行。

直到修复完报错就可以打包，详情看视频

使用openclaw修复

安装openclaw需要安装node环境必须安装：

Node.js --- Download Node.js®

openclaw安装命令：

npm install -g openclaw@latest

openclaw配置：第一次需要修改配置好，参考我的配置你搞别的中转：

openclaw启动：

openclaw gateway run

使用claude修复代码：

Ccswitch：

Releases · farion1231/cc-switch · GitHub

npm install -g @anthropic-ai/claude-code

claude --version

总结：

环境配置问题：maven 环境，jdk ，lib引用依赖
Ai工具选择：cursor（多窗口同步进行，openclaw自动化任务，claude写代码强，逆向修复很慢烧toekn）
自动化逆向工具（98%报错）
送一次自动化逆向，跑源码（买了课程同学 xyjsph），如果需要看详情或者视频学习的联系小杨。
