javamavensonarqube
When I build my maven project locally, I run a sonar check. I am getting the following error. Googling hasn't resolved the issue.
I am new to SonarQube – am I missing config?
[ERROR] Failed to execute goal
org.sonarsource.scanner.maven:sonar-maven-plugin:3.3.0.603:sonar
(default-cli) on project x: Unable to execute SonarQube: Fail to get
bootstrap index from server: Failed to connect to

If I understand correctly your issue, I think that what you are looking for is the sonar.core.serverBaseUrl property that you can set in the global administration settings:
This is the "public" URL of your SonarQube instance that will be used in the logs or in the notifications.
SonarQube 5.6 requires at least Java 8 (see requirements). Note that this is not a just a requirement on the server side, it's also required on the client side where analysis are ran.
Like agabrys mentioned in his comment, the Unsupported major.minor is a classic Java error (see this thread).

The SonarQube Scanners don't run in isolation to analyze your code. They interact with a SonarQube server, and language analyzers loaded in that server.
To run an initial trial, download the latest version from sonarqube.org, expand the resulting zip, and start the server. Then you'll be able to successfully run a scan.
Note that the instructions I've just given you start the server with a for-trial-only on-board H2 database. You should not go into production with that database.
