error invalid source option, source is either '1.3' or '1.4': Browserstack integration with Azure Devops Pipeline - browserstack

Question

I am trying to integrate browserstack with azure devops pipelines. I added all the necessary repos to the pom.xml While building the code i am getting below error. And i am following this link https://www.browserstack.com/docs/automate/selenium/azure-pipelines#java
I keep on getting the source failure and says 1.3 or 1.4 i am using Jdk 1.8 version. I defined jdk source as 1.8 and jdk target as 1.8
