How to create a job in spring-xd using java config only - spring-xd

Question

Is there any example of using spring xd with pure java config (no xml).
I created a simple tasklet, jarred the same (whojob.jar) and put it into the lib folder.
The xml config is below. I put this in a file called whojob which is in the modules/job folder and also jarred with my whojob.jar.
When I try to create a job:- (:>job create --name mywhojob --definition "whojob") I get the error :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.config.TransformerFactoryBean#0': Cannot create inner bean 'org.springframework.xd.dirt.plugins.job.JobLaunchRequestTransformer#0' of type [org.springframework.xd.dirt.plugins.job.JobLaunchRequestTransformer] while setting bean property 'targetObject'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.xd.dirt.plugins.job.JobLaunchRequestTransformer#0' defined in class path resource [META-INF/spring-xd/plugins/job/job-module-beans.xml]: Cannot resolve reference to bean 'jobFactoryBean' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobFactoryBean': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: No Batch Job found in registry for the provided key 'mywhojob.job'.
My xml config is below. If possible I would like to have a pure java solution.
Thanks

Here is a sample that uses XD job with the batch tasklet defined in an external jar file.
https://github.com/ilayaperumalg/spring-xd-batch-sample
To create jar, from the repo root directory, just run: ./gradlew build
To make it easier, I have also copied the job module "myjob" (which uses the above tasklet) into the repo. You can just copy this 'myjob' into your $XD_HOME/modules/job/.
Give it a try using XD version M6 or the latest master, and let us know if you have any question.
