Sonar - Fail to request server version | HTTP Status 404

Question

I'm setting up a sonar system for Java. My local test SonarServer 4.0 successfully connect and process my antscript (I'm using "sonar-ant-task-2.2.jar"). But my target server 3.7.3 won't even provide the server version.

I tried the given http://... from the given errormessage and my browser (firefox) is showing the correct server version.

Can someone help me out with this one ? Thx :)

EDIT: Sorry but after a restart I can't reproduce this error above. Now I can't even connect to the server :O After some restarts later I still get this error - for not connecting

Answer 1

I too had the same issue and resolved it. Check the SonarQube server's following properties (you may find it in - SONAR_INSTALATION_DIR/conf/sonar.properties)

sonar.web.host=localhost
sonar.web.port=9000
sonar.web.context=/sonar

Then check your Sonar-runner's configuration(You may find it in - SONAR-RUNNER-INSTALLATION-DIR/conf/sonar-runner.properties)

sonar.host.url=http://localhost:9000/sonar

Make sure the sonar.host.url was composed using the above three properties from the SonarQube's properties as shown here. In your case make sure you have the values as explained here.

Answer 2

I don't know how, but the server was secured to allow only http requests. So the problem was an adminstration problem only.

Answer 3

seems that your server can not connect, you can do the two following operation: 1. check your sonar server port had been listening.. 2. restart the sonar server, if your environment need mysql first, restart mysql first.
