Quartz HelloJob

Question

I am new to Quartz and I'm running into a compiling error. I am simply trying to get the HelloJob to run based on Quartz's Lesson 1 for Hello World. I am having trouble declaring a JobDetail with the error: The method newJob(Class<? extends Job>) in the type JobBuilder is not applicable for the arguments (Class)".

Originally, the code had 3 errors at newJob, newTrigger, and simpleSchedule was

// define the job and tie it to our HelloJob class
JobDetail job = newJob(HelloJob.class)
    .withIdentity("job1", "group1")
    .build();

// Trigger the job to run now, and then repeat every 40 seconds
Trigger trigger = newTrigger()
    .withIdentity("trigger1", "group1")
    .startNow()
    .withSchedule(simpleSchedule()
            .withIntervalInSeconds(40)
            .repeatForever())            
    .build();

without JobBuilder.newJob(...), TriggerBuilder.newTrigger(...), SimpleScheduleBuilder.simpleSchedule(...). Unlike the example given, I went ahead and added the imports and attached the class calls in front of newJob, newTrigger, etc. which got rid of 2/3 errors. But it seems the error persists with

 JobDetail job = JobBuilder.newJob(HelloJob.class)
        .withIdentity("job1", "group1")
        .build();

I have also tried replacing my job declaration with

JobDetail job = new JobDetail("job1", "group1", HelloJob.class);

but that ends with Cannot instantiate the type JobDetail and it seems like a few examples out there do this.

Will really appreciate clarification,

Thanks!

You need to have this line of code:

import static org.quartz.JobBuilder.*;

And then in should work. Hopefully.

Edit: AND MAKE SURE 'HELLOJOB' IMPLEMENTS JOB!!

There.
