SonarQube version : 7.3
Sonarscanner for MSBuild : 4.0.2

I am trying to run Sonarscanner for MSbuild using Teamcity and during the begin step I get the following error. My Sonarqube service is running with LocalAccount. This is an upgrade from an earlier version, The project died out and I recently started it with the old database. I successfully upgraded the version and the database to SQLServer 2017.

Check the value you are specifying for sonar.host.url. It looks like a database connection string rather than a URL.

It is no longer necessary to specify the database connection details when analysing (since SonarQube v5.2). Now you just need to provide the server URL (and credentials, unless anonymous access is allowed).

Thank you, This fixed the issue

How can I determine what should be the Xmx value? Do you have any calculation to the size of the project vs the Xmx value?

Hi,

For separate question please raise topics, otherwise it’s hard for everybody to track discussions and contribute effectively. Before you raise a specific topic though, I strongly suggest browsing existing discussions on this topic, notably:
