+.SYNOPSIS
+    Updates parent-level and root-level pom.xml files, and ci.yml for a Java SDK package.
+
+.DESCRIPTION
+    This script handles two cases:
+    Case 1 - Service exists, new resourcemanager package:
+        - Skips root pom (service already listed)
+        - Updates service-level pom.xml with new module
+        - Updates ci.yml with new artifact entry
+    Case 2 - Brand new service:
+        - Updates root pom.xml with new service module
+        - Creates service-level pom.xml from template
+        - Creates ci.yml from template with new artifact entry
+
+.PARAMETER PackagePath
+    Absolute path to the root folder of the local SDK project (containing pom.xml).
+
+.PARAMETER SdkRepoPath
+    Absolute path to the root folder of the local SDK repository.
