My Job configuration looks like this:
#EnableBatchProcessing
public class JobConfiguration {
#Bean
public Job importJob() {
return jobBuilderFactory.get("Import-Products").incrementer(new RunIdIncrementer())
.flow(step1())
.next(step2())
.end()
.build();
}
}
As far as i found out, a JobParametersIncrementor is supposed to fix this exception by adding a incrementing runId to the parameters. But in my case i can only run the job once on the server, then i have to clear the database (mysql) and the RunId is nowhere in the database.

Answer 1

As #Michael Minela already guessed my jobs where started with the wrong docker image-version. So the RunIdIncrementer was not present and it did not work.
After registering a new app with the correct version everything worked. Thanks.
