Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

Few small changes requested - thanks!

• thanks to the help of @krisstern , I am now able to preview the changes I've made without any errors. I can see the version at the footer now , but the thing is it shows :
  [999999-SNAPSHOT (private-9bfa0ac3-Lenovo)
  What could be the reason for this?

That's the SNAPSHOT version when running locally, once it's deployed it'll show the actual release version. Nothing to worry about :)

You need to remove this if block as Jenkins cannot be null. (My first assumption was wrong. Jenkins null handling actually is very ugly)

Added the desired changes , now it's failing because of that spotless issue. I had applied mvn spotless:apply locally then pushed however this showed error when pushed. This has happened to me before too , I don't know why.

Thanks for your guidance @uhafner @janfaracik . I've applied the required changes. If further changes are needed , I can work on them too.

[janfaracik]

Made a couple small tweaks, looks good to me! Thanks for contributing. I'll merge if you're happy @uhafner

[uhafner]

Now the null handling is fine! Thanks for the PR!
