Fixing the 'analyze' and 'analyze-report' ITs under JDK 8: they must not force the declaration of maven-artifact as a used dependency, because JDK 8 now writes bytecode entries for constants and maven-dependency-analyzer fails the build in that case. This commit also adds a specific IT for the 'usedDependencies' parameter, leveraging a source retention annotation.
