how to start only one job in a task in spring cloud dataflow

I have a simple task which has 2 jobs. When I run the task Job 1 and Job 2 run one after another. How can I configure it in a way so that when I pass the job name only that job runs?

By default, Spring Boot executes all jobs in the application context at startup (See here). If you want to execute only one job, you need to specify its name using the spring.batch.job.names property.

In your case, you can add a task argument and specify which job want to run. For example: if your task contains two jobs job1 and job2, you can add the task argument --spring.batch.job.names=job1 to run only job1:

sct-argument

Make sure to add -- to the key. The command that will be executed by SCDF server should be something like:

2018-09-10 12:23:45.932  INFO 57560 --- [nio-9393-exec-1] o.s.c.d.spi.local.LocalTaskLauncher      : Command to be executed: java -jar myjob.jar --spring.batch.job.names=job1 --spring.cloud.task.executionid=1

With this argument, only job1 should be executed.

Hope this helps.
