Ant - Unable to reach Sonar server via https

[navraj28]

I am working on 2 projects - one using Maven the other Ant. The Maven scan is going fine. The Ant scan is giving error related to certificate, though both use the same Truststore.
Maven command (works):
mvn sonar:sonar -Djavax.net.ssl.trustStore=C:\Naveen\keystore.jks -Djavax.net.ssl.trustStorePassword=XXX -Dsonar.host.url=https://sonarqube.xxx.com -Dsonar.login=rajannn -Dsonar.password=XYZ

Ant command (fails with unable to find valid certification path to requested target)
ant sonar -Djavax.net.ssl.trustStore=C:\Naveen\keystore.jks -Djavax.net.ssl.trustStorePassword=XXX -Dsonar.host.url=https://sonarqube.xxx.com -Dsonar.login=rajannn -Dsonar.password=ZYZ

Additional detail:
JDK java-11-openjdk-11.0.6-2
Server Developer Edition Version 8.4.2 (build 36762)

I don't understand why you're asking questions about Maven or Ant - this has absolutely nothing to do with this project.
