How to prevent Spring Batch Job to from being restarted on step fail?

I have simple single-step job:

@Bean(name = "restProcessorJob")
public Job job(@Qualifier("step") Step step) throws Exception {
    return jobBuilderFactory.get("restProcessorJob")
            .start(step)
            .build();
}

And if there was exception during step execution, Batch framework will try to execute it again immediately.

...

Is there any way to configure such behavior and do not run the job twice on fail?

EDIT:

It seems that I've found the source of problem. Spring boot application tries to launch every CommandLineRunner it founds in the context. In my case it is the org.springframework.boot.autoconfigure.batch.JobLauncherCommandLineRunner. I have been trying to exclude this class:

@EnableAutoConfiguration(excludeName="org.springframework.boot.autoconfigure.batch.JobLauncherCommandLineRunner")

But without success...

Use .preventRestart with an incrementer 

@Bean(name = "restProcessorJob")
public Job job(@Qualifier("step") Step step) throws Exception {
    return jobBuilderFactory.get("restProcessorJob")
            .start(step)
            .incrementer(new RunIdIncrementer())
            .preventRestart()
            .build();
}

You can configure it in your config file, you can put the skip limit to 0
