+/**
+ * Generate resources from yang files using user provided set of
+ * {@link ResourceGenerator}s. Can be used to copy yang files that served as
+ * blueprint for code generation into resources directory. Steps of this
+ * process:
+ * <ol>
+ * <li>List yang files from {@link #yangFilesRootDir} (If this goal is in the
+ * same execution as generate-sources, the same cached list will be used and the
+ * root folder will not be searched for yang files twice)</li>
+ * <li>For each {@link ResourceGenerator} from {@link #resourceProviders}:</li>
+ * <ol>
+ * <li>Instantiate using default constructor</li>
+ * <li>Call {@link ResourceGenerator#generateResourceFiles(Collection, File)}</li>
+ * </ol>
+ * </ol>
