all tests pass. but getting Maven build failure

[Styris]

I just ran some selenium/appium tests using mvn test and all the tests were executed and all were passed. However at the end of the test I got an unexpected build failure message that put me off. And it will confuse other stakeholders too when they look at it. Here is what I got:

[ERROR] Failed to execute goal net.masterthought:maven-cucumber-reporting:2.0.0:generate (execution) on project IOS_Automation: Error Found: BUILD FAILED - Check Report For Details -> [Help 1]

[ERROR] 

[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR] Re-run Maven using the -X switch to enable full debug logging.

I am pasting my POM.xml file here so that someone could please look and advise on whats wrong:

Also another error that I get is:

Could not parse build number: ${${build.number}}.

java.lang.NumberFormatException: For input string: "${${build.number}}"
