默认插件sonar-java中注册了ExternalReportExtensions.define(context);针对三大插件的Sensor——
context.addExtension(CheckstyleSensor.class);
context.addExtension(PmdSensor.class);
context.addExtension(SpotBugsSensor.class);
默认执行阶段是在对文件本地的扫描扫描之后调用执行——

这样还是不能倒推到报错的堆栈信息上啊？-_-|| 看起来还得加上 https://github.com/SonarSource/sonarqube/这里的代码才能梳理出来完整逻辑。先缓缓
重新读了一下执行逻辑，不需要sonarqube端的代码。sonar-scanner-cli只是简单做了一个壳，执行的逻辑依赖sonar-scanner-api。跟踪以下调用链路即可，包含了这两个工程的代码。
核心是通过proxy的方式，调用了org.sonarsource.scanner.api.internal.batch.BatchIsolatedLauncher类的execute方法。IsolatedLauncherProxy是代理执行的InvocationHandler

根据使用scanner执行一次正常的操作，结合log输出更方便理解。sonar-scanner-cli工程就是发布的sonar-scanner工具的源码，只是在发布时，根据不同的平台增加了一个jre的执行环境
