Elasticsearch error when running Sonarqube 6.7 on Windows

Question

I'm using JDK 1.8.0_161 as the Java runtime. When I run the StartSonar.bat I get the following exception:

Answer 1

On the loglevel, you can see that this is a WARN message.

The real error is caused by something else.

Check the sonarqube\logs folder for details.

Answer 2

Please check your web log file inside the logs folder(C:\sonarqube\logs). Sonarqube is trying to use a port which is already occupied, force kill the port worked for me.
