+ * Version of SonarQube at runtime. This component can be injected as a dependency

+ * while keeping backward-compatibility with previous versions of SonarQube.
+ * <br><br>
+ * 
+ * Example 1: a {@link Sensor} wants to use an API introduced in version 5.5 and still requires to support older versions
+ * at runtime.
+ * <pre>
+ * public class MySensor implements Sensor {
+ *
+ *   public void execute(SensorContext context) {

+ *       context.newMethodIntroducedIn5_5();
+ *     }
+ *   }
+ * }
+ * </pre>
+ *
+ * Example 2: a plugin needs to use an API introduced in version 5.6 ({@code AnApi} in the following
+ * snippet) and still requires to support version 5.5 at runtime.
+ * <br>
+ * <pre>
+ * // Component provided by sonar-plugin-api
+ * // @since 5.5
+ * public interface AnApi {
+ *   // implicitly since 5.5
+ *   public void foo();
+ *
+ *   // @since 5.6

+ *     this.runtimeApiVersion = runtimeApiVersion;
+ *     this.api = api;
+ *   }
+ *
+ *   public void doSomething() {
+ *     // assume that runtime is 5.5+
+ *     api.foo();
+ *
+ *     if (runtimeApiVersion.isGreaterThanOrEqual(SonarQubeVersion.V5_6)) {
+ *       api.bar();
+ *     }
+ *   }
+ * }
+ * </pre>
+ * <p>
+ * The minimal supported version of plugin API is verified at runtime. As plugin is built
+ * with sonar-plugin-api 5.6, we assume that the plugin requires v5.6 or greater at runtime.
+ * For this reason the plugin must default which is the minimal supported version
+ * in the configuration of sonar-packaging-maven-plugin 1.16+:
