Error during SonarQube scanner execution, Unsupported Java version for PMD:

I am unable to execute sonar analysis for PMD. I have installed a plugin for pmd (sonar-pmd-plugin-3.2.1.jar) manually and restarted the sonarqube. triggered jenkins build for the pmd analysis where it throw the error, unsupported java version for pmd. Please find snippet for reference.

Here are details for the plugins I have used:

SonarQube : 7.1
Jenkins : 2.164
PMD plugin : sonar-pmd-plugin-3.2.1.jar (manually placed under extensions folder in SonarQube)
Java Plugin: sonar-java-plugin-5.2.0.13398.jar (under extensions folder in SonarQube)
Sonar scanner: sonar-scanner-4.2.0.1873-linux
JDK : 1.8

Work around:

• Have tried adding below both entries in sonar-scanner.properties file.

  sonar.java.source=1.8
  sonar.java.source=8
  

• Have changed multiple plugins for PMD and JAVA under SonarQube, here are the reference of plugin versions:

  

  

I have attached the Jenkins build logs.
