Spring Batch Admin (2.0.0.M1): error creating bean batchMBeanExporter

Question

I am trying to run spring batch admin from spring boot application.

I am using this excellent example from Michael (@mminella). This application works fine.

However, I need similar application using maven; I went ahead and created one with same files, jobs, configs and dependencies. But I ended up in following exception.

Only difference I see is the version of spring-batch-core. With maven it's version is 3.0.6 while with gradle (Michael's application) has 3.0.4.

Not sure what's going on when I use maven; really appreciate your help. Please let me know if any additional details required.

Looking forward for your inputs.

Thank you,
