Hi,
The SonarScanner for Maven is a Maven plugin. It work better when part of the build reactor:
mvn package sonar:sonar
That's why the configuration is different than for MSBuild projects.
You should make the owasp dependency checker part of the Maven build, for example using
this plugin. Since the SonarScanner is an aggregator mojo, it will run at the end, after DepCheck reports are produced.
