Could you check if your classpath include the following JARs:

• elasticjob-infra-common
• elasticjob-error-handler-general

[candyYu]

i add it, now my dependency are <groupId>org.apache.shardingsphere.elasticjob</groupId> <artifactId>elasticjob-lite-core</artifactId> ${elasticjob-version} <groupId>org.apache.shardingsphere.elasticjob</groupId> <artifactId>elasticjob-dataflow-executor</artifactId> ${elasticjob-version} <groupId>org.apache.shardingsphere.elasticjob</groupId> <artifactId>elasticjob-simple-executor</artifactId> ${elasticjob-version} <groupId>org.apache.shardingsphere.elasticjob</groupId> <artifactId>elasticjob-infra-common</artifactId> ${elasticjob-version} <groupId>org.apache.shardingsphere.elasticjob</groupId> <artifactId>elasticjob-error-handler-general</artifactId> ${elasticjob-version}

but i got the same error

Job (DEFAULT.ScheduleJob ) before Quartz Scheduler (v2.2.1) 'ScheduleJob' does this matter?

[candyYu]

what depedency i forgot to import? I got the error next, i can run in my idea when i run it with java -jar i got the next error

Exception in thread "main" org.apache.shardingsphere.elasticjob.infra.yaml.exception.YamlConfigurationConverterNotFoundException: No YamlConfigurationConverter found for class [org.apache.shardingsphere.elasticjob.tracing.api.TracingConfiguration] at org.apache.shardingsphere.elasticjob.infra.pojo.JobConfigurationPOJO.lambda$null$0(JobConfigurationPOJO.java:121) at java.util.Optional.orElseThrow(Optional.java:290)

Could you check if your classpath include the following JARs:

• elasticjob-infra-common
• elasticjob-error-handler-general

Since you have configured TracingConfiguration, check if your classpath include the following JARs:

• elasticjob-tracing-api
• elasticjob-tracing-rdb

i also get the same error when i run it with java -jar 16:51:35.005 [MySimpleJob_Worker-1] DEBUG org.quartz.core.JobRunShell - Calling execute on job DEFAULT.MySimpleJob 16:51:35.007 [MySimpleJob_Worker-1] ERROR org.quartz.core.JobRunShell - Job DEFAULT.MySimpleJob threw an unhandled Exception: java.lang.NullPointerException: null at org.apache.shardingsphere.elasticjob.executor.context.ExecutorContext.get(ExecutorContext.java:75) at org.apache.shardingsphere.elasticjob.executor.ElasticJobExecutor.execute(ElasticJobExecutor.java:79) at org.apache.shardingsphere.elasticjob.lite.internal.schedule.LiteJob.execute(LiteJob.java:35) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:573) 16:51:35.007 [MySimpleJob_Worker-1] ERROR org.quartz.core.ErrorLogger - Job (DEFAULT.MySimpleJob threw an exception. org.quartz.SchedulerException: Job threw an unhandled exception. at org.quartz.core.JobRunShell.run(JobRunShell.java:213) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:573) Caused by: java.lang.NullPointerException: null at org.apache.shardingsphere.elasticjob.executor.context.ExecutorContext.get(ExecutorContext.java:75) at org.apache.shardingsphere.elasticjob.executor.ElasticJobExecutor.execute(ElasticJobExecutor.java:79) at org.apache.shardingsphere.elasticjob.lite.internal.schedule.LiteJob.execute(LiteJob.java:35) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) ... 1 common frames omitted
