I have maven installed on my local machine and I\'m trying to test out Sonar installed on a remote box.
I found a few post online to configure settings.xml
As explained you need to specify the JDBC connection details, otherwise Sonar will attempt to talk to the embedded Derby instance, it assumes is running on localhost.
Are you using Derby? Well, the default configuration of Derby does not accept remote connections, but only connections from the same host.
The SONAR-1039 issue explains how to work-around this problem, but my advise would be to setup a full-blown database such as MySQL or Postgresql.
