Description

If a batch job throws an arbitrary exception, i think the CLI batchrunner show return a non-zero exit status per default.

I know, throwing an custom RuntimeException annotated with org.apache.batchee.cli.command.api.Exit will do the trick. But wrapping every reader, processor, writer and batchlet in a big try-catch block sounds a bit ugly.

I would suggest wrapping the whole org.apache.batchee.cli.bootstrap.Bootstrap#main in a try-catch block, catching Exception, printing the stacktrace and exiting with some default non-zero exit status.
