Unable to start sonarqube java.net.ConnectException

SonarQube Server / Community Build

I have installed sonarqube 7.7 on windows 10 but when I’m trying to start the sonarqube server using the StartSonar.bat file It is giving me the following error

wrapper  | --> Wrapper Started as Console

My Java version is

Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

I’m not able to figure out what is going wrong. Please help

Hello @sachinmukherjee,

A user ran into this issue in the past (SonarQube 6.7.5 startup failure: Failed to connect to the Wrapper at port 0 - #8 by shivdewangan). He was using a network drive which is not supported.
Any chance that you are doing the same here?

Note that the error:

comes from the underlying component SQ uses (Tanuki Wrapper) which apparently fails to instantiate a JVM to launch other SQ processes.

Cheers

Hello @Antoine.

No, I’m trying to run it in my local drive i.e C drive.

Hello @sachinmukherjee,

Ok. First thing, I can see you’re trying to run SQ 7.7 which is an unsupported version now. If you want to stick to the LTS, please use 7.9 (patch release 7.9.4), or to the latest version please use 8.5.
Both requires Java 11 (I can see you were using Java 8 here).

If the issue still appears on your new install, you can use wrapper.debug=true in the wrapper.conf. This will output in sonar.log what exactly the wrapper does and where it fails. I’m sure from here you will be able to understand what is the problem.

Cheers,

Hello @Antoine

I followed the above steps. Downloaded sonarqube 8.4 and installed java 11 still I’m getting the same error. I have gone through the logs too but not able to figure out what is missing. I have attached the logs. Please helpsonar.log (7.6 KB)

Hello @sachinmukherjee,

We checked around here and we never heard of such report in the past. As you are in a Windows environment, it’s possible that you have an Antivirus which is blocking some communication, even though they are local.
If that’s the case, please deactivate (of course temporarily, just to understand) any kind of security mechanism you may have and try again.

I hope this will help.

Antoine
