### 简介
+ jacoco二开，主要加入了增量代码匹配的功能 具体设计方案参考  [jacoco增量代码实践](https://blog.csdn.net/tushuping/article/details/112613528) 

### 改造内容：
+ 新增类：所有新增类处于org.jacoco.core.internal.diff包下面；
+ 修改类：主要修改了核心类org.jacoco.core.analysis.Analyzer,org.jacoco.core.analysis.CoverageBuilder;org.jacoco.core.internal.flowClassProbesAdapter
+ 所有修改内容在commit记录可查，为了方便查看，我尽量减少了commit的次数

### 使用方法
###### 1、 下载源码，然后运行maven: mvn package   -Dmaven.test.skip=true   -Dmaven.javadoc.skip=true
###### 2、 其他包都可以使用jacoco官方包，report时使用我们构建的包，如果是增量覆盖率加入参数--diffCode=

由于对象格式的通用性，可以配合 [差异代码获取](https://github.com/rayduan/code-diff.git) 一起使用


###### 3、关于生成多模块工程中jacoco报告命令参考 demo ：
java -jar org.jacoco.cli-0.8.7-SNAPSHOT-nodeps.jar    report jacoco.exec 
--classfiles \Desktop\feigin\web\build\classes   
--classfiles \Desktop\feigin\biz\build\classes   
--classfiles \Desktop\feigin\base\build\classes 
--sourcefiles \Desktop\feigin\web\src\main\java  
--sourcefiles \Desktop\feigin\biz\src\main\java   
--sourcefiles \Desktop\feigin\base\src\main\java --html report --xml jacoco.xml   
--diffCode=[{
      "classFile": "com/vx/crm/web/swagger/SwaggerConfig",
      "methodInfos": [
        {
          "methodName": "apiInfo",
          "parameters": ""
        }
      ],
      "type": "MODIFY"
    }]    
--encoding=utf8

###### 4、jacoco报告如存在乱码问题：  请执行命令时带入参数  --encoding=utf8
