+                                                🚫 Java version error: This project requires Java ${java.version} or higher.

+                                                Your current Java version is ${java.version}
+                                                To fix this:
+                                                1. Download and install Java 17 or higher from your preferred vendor
+                                                2. Make sure JAVA_HOME points to the new Java installation
+                                                3. Verify with 'java -version' command
+                                                4. Run the build again
