Prev	Part II. Tasks	Next

A batch job task that executes 2 jobs each job prints out the job name and a timestamp to stdout. Intended to primarily be used for testing.

3.1 Options

The timestamp task has the following options:

timestamp.format: The timestamp format, "yyyy-MM-dd HH:mm:ss.SSS" by default. (String, default: yyyy-MM-dd HH:mm:ss.SSS)

3.2 Building with Maven

$ ./mvnw clean install -PgenerateApps
$ cd apps/timestamp-batch-task
$ ./mvnw clean package

3.3 Example

java -jar timestamp-batch-task-<version>.jar

	Warning
Launching a composed task with timestamp-batch app as it is, more than once, may lead task into ERROR status. This is due to JobInstanceAlreadyCompleteException, as JobInstance won’t be unique, if JobParameters remain the same. One of the way to handle this is to utilize JobParametersIncrementer as below: jobBuilderFactory.get("job1").incrementer(new RunIdIncrementer()) jobBuilderFactory.get("job2").incrementer(new RunIdIncrementer()) In this case RunIdIncrementer will allow the app to be launched multiple times, each having its own JobInstance
