+## Building All Projects
+
+To quickly verify that all Maven projects build successfully, you can use the provided build script:
+
+```bash
+./build-all.sh
+```
+
+This script will:
+- Check your Java version
+- Build all Maven-based sample projects
+- Provide a summary of successful and failed builds
+
+**Requirements**: Java 17 or later
+
