Fail to instantiate class [com.buransky.plugins.scoverage.ScoveragePlugin] of plugin [scoverage]

[shobancs]

Hi,

We have large number of users are using Java plugin in our sonar instance and we have a team using scala api as dependency in Java maven modules which is causing Jenkins build failure as scoverage plugun is not initiated during the build, we are using sonar maven goals to analyse source and publish sonar reports.
Sonar version : 5.6..3
Sonar_info_5.6.3.zip

Jenkins build erro logs:
