@snicoll can you guide me to what exactly needs to be done as part of this task. I want to do my open source contribution

Thanks for the offer @ManikantaKandagatla but we prefer to do dependency upgrades ourselves. There's nothing that can be done at this time as Spring Batch 4.3.7 hasn't been released yet and this task is straightforward (removing -SNAPSHOT from a build file).
