Java Quartz Logging功能禁用源代码，不包括日志库

我正在开发一个Java应用程序，并希望使用Quartz Scheduling功能。我获得最新版本2.2.1并尝试从记录的示例开始。我停止了Quartz的日志系统集成。
我的Java应用程序没有记录（使用我的特殊的非标准日志记录库），并且不想使用Log4J.But Quartz通过下面的消息请求它。如何通过编写代码（无xml文件或其他）来设置禁用日志记录功能的Quartz。我不想将任何日志jar库包含到我的应用程序中。Java Quartz Logging功能禁用源代码，不包括日志库

SchedulerFactory sf = new StdSchedulerFactory(); 
    Scheduler sched = sf.getScheduler(); 

JobDetail job = JobBuilder.newJob(Job.class) 
     .withIdentity("job1", "group1") 
     .build(); 
CronTrigger trigger = TriggerBuilder.newTrigger() 
     .withIdentity("trigger1", "group1") 
     .withSchedule(CronScheduleBuilder.cronSchedule("0/20 * * * * ?")) 
     .build(); 
sched.scheduleJob(job, trigger);

，并得到错误

由于Quartz使用SLF4J，你必须把它配置为使用NOPLogger（无操作记录仪，一个什么也不做“虚拟日志”）。奇怪的是这是默认配置，所以请确保您的项目中没有配置文件
