org.jkiss.dbeaver.ui.controls.sqlinspection.SqlInspectionCommandHandler 这个类是定义好的，是在plug-in org.jkiss.dbeaver.ui.editors.sql 项目中 

 

 

但是该类最终会在 org.jkiss.dbeaver.core plug-in 项目中引用，所以，这个类需要在 org.jkiss.dbeaver.ui.editors.sql 项目中暴露出来，因此在 org.jkiss.dbeaver.ui.editors.sql 项目的plugin.xml 中配置对外暴露的类

 

 配置好后最后如下：

 

 代码运行，断点成功执行到想要的位置

 做完以上操作后，不要忘记右击项目，选择maven---> update project
