Unable to login to BuildOn UI due to DB connection issue

Cause

08-May-2018 11:48:45.572 SEVERE [http-nio-8080-exec-3] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [com.cognizant.buildon.controller.AuthenticationWebController] in context with path [/buildon] threw exception [Servlet execution threw an exception] with root cause

There may be an authentication failure due to invalid postgres DB credentials configured in buildon.properties. Update correct values for DB properties in buildon.properties and persistence.xml

Fix

hibernate-c3p0 jar conflicts with com.mchange c3p0 jar. Excluded com.mchange.c3p0 jar in pom.xml as shown below.
