Quartz 2.0 调度程序异常
我们使用的是quartz 2.0框架。我刚刚下载了quartz包并将其放置在我的项目的构建路径中。如果我执行与quartz 1.6相同的调度程序，它会抛出以下异常：
Exception in thread "main" java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
at org.quartz.impl.StdSchedulerFactory.<init>(StdSchedulerFactory.java:274)
at org.quartz.impl.StdSchedulerFactory.getDefaultScheduler(StdSchedulerFactory.java:1480)
at QuartzTest.main(QuartzTest.java:10)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:346)
at java.lang.ClassLoader.loadClass(ClassLoader.java:609)

我的代码到目前为止，如果只是启动和停止调度程序。如果有人能帮助我解决这个问题，我将不胜感激。
同样在 2.x 版本中，我们为 jobdetail 创建对象的方式似乎有点不同。如果我以这种方式创建一个对象：
JobDetail jobDetail = new JobDetail("jobDetail-s1", "jobDetailGroup-s1", SimpleQuartzJob.class);
IDE 说..无法实例化 JobDetail 类型。
请帮忙。
we are using quartz 2.0 framework. I just downloaded quartz packages and placed it in the build path of my project. If i execute the same schedular i used for quartz 1.6, it is throwing the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
at org.quartz.impl.StdSchedulerFactory.<init>(StdSchedulerFactory.java:274)

My code as of now, if just starting and stopping schedular. I will appreciate, if any body could help me out in this.
Also in 2.x version, the way we would create an object for jobdetail seems to be a bit different. If i create an object in this manner:
JobDetail jobDetail = new JobDetail("jobDetail-s1", "jobDetailGroup-s1", SimpleQuartzJob.class);
IDE says ..cannot instantiate the type JobDetail.
Please, help.

请注意，在 Spring 3.1 发布之前，Spring 3 分支不支持 Quartz 2.0
请参阅此处（Spring 发行说明）。
这也让我抓狂，因为他们的示例和我们的旧代码不再起作用。我以为我们损坏了某些东西，但损坏它的是 Spring/Quartz。我切换回 Quartz 1.5.2 和 Spring 3.0.5，一切正常。
Spring 教条变幻莫测的另一个例子。
Note that Quartz 2.0 is not supported by Spring 3 branch until the release of Spring 3.1
See here (Spring release notes).
This drove me nuts too as their examples and our old code did not work anymore. I assumed that we'd broken something, however it was Spring/Quartz that broke it. I switched back to Quartz 1.5.2 and Spring 3.0.5 and everything works well.
Another example of the vagaries of Spring dogma.
