Issue
I have a Spring Batch job with is now giving me an error: Failed to serialize object of type: class org.springframework.batch.core.StepExecution the Job Listener is printing the following exception:
org.springframework.batch.core.JobExecutionException: Flow execution ended unexpectedly

The configuration is as follows:
<job id="job2" restartable="false" job-repository="jobRepository" parent="baseJob">
<step id="job2StepBootstrap" parent="parentJobStep">
<tasklet ref="job2TaskBootstrap" transaction-manager="jobsTransactionManager" />
</step>
<listeners>
<listener ref="job2JobListener"/>
</listeners>
More
<bean id="jobsTransactionManager"
class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
<bean id="jobRepository"
class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
<property name="transactionManager" ref="jobsTransactionManager" />
<property name="isolationLevelForCreate" value="ISOLATION_SERIALIZABLE" />
<property name="validateTransactionState" value="false"/>
its not so obvious to me what is wrong, i really appreciate your help. I dont want to save the jobs metadata at all.
public class BatchDeploymentTaskBootstrap implements Tasklet, Serializable{
@Override
public RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {
System.out.println("Running Batch Job Task(%s)... ");
return RepeatStatus.FINISHED;
}
}
I have added the job2TaskBootstrap as you can see even the stripped down version doesn't work.
The complete stack trace printed from the job listener afterJob method.

Solution
One or more of your classes used in your step is missing an implements Serializable in the class declaration.
Anything saved to the jobRepository needs to be serializable. This may be used as part of the step execution context data that is saved.
