How to use external sonar server for jHipster project - spring

Question

I am currently developing a spring boot application with jHipster and I want to use an existing sonar server from my company to analyze the code. JHipster only describes a way to use a build in sonar server from a docker container. Unfortunately that is not an option for me since my machine is running on Windows Server 2012, that is not supported by docker.
I already tried to start the maven build by adding the server url as a build parameter to the maven build, but it is ignoring it.
mvn clean test sonar:sonar -Dsonar.host.url=http://server-ip:server-port/ -Dsonar.login=login -Dsonar.password=pw
I am relatively new to the topic and was using the given command by the jhipster reference page (https://jhipster.github.io/code-quality/), so the test profile should be the correct one for this purpose.
When I run the command it ignores the given url paramter and still tries to use localhost where it expects the sonar in a docker container.

Since jHipster generates and configures a lot in the background I have no idea if I am missing something vital here. Maybe a configuration file I have to adjust? I really appreciate the help.
The pom.xml was generated by jHipster and the maven plugin is configured as followed:
<plugin>
<groupId>org.sonarsource.scanner.maven</groupId>
<artifactId>sonar-maven-plugin</artifactId>
<version>${sonar-maven-plugin.version}</version>
</plugin>
The version is set in the properties as:
<sonar-maven-plugin.version>3.2</sonar-maven-plugin.version>
I tried setting up my project on a linux vm with a running local docker sonar instance as suggested by the jHipster team and it was running fine, it is just very inconvenient for me since I have an available company sonar instance running in the intranet.
I also tried modifying my settings.xml as suggested and that was ignored, though it lead to a different looking error message:

Answer 1

Everything is explained in the sonar docs : https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner+for+Maven
You should edit the settings.xml file in you ~/.m2directory with the following:
<settings>
<pluginGroups>
<pluginGroup>org.sonarsource.scanner.maven</pluginGroup>
</pluginGroups>
<profiles>
<profile>
<id>sonar</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<!-- Optional URL to server. Default value is http://localhost:9000 -->
<sonar.host.url>
http://myserver:9000
</sonar.host.url>
</properties>
</profile>
</profiles>
</settings>

Answer 2

Try to add the following line into the properties section of your pom.xml file.
<sonar.host.url>http://1.2.3.4:9000/</sonar.host.url>
With the IP address corresponding to your sonarqube server.
