+How to Use
+
+[1] Move The Two scripts to a Last location
+1. pack_offline_bundle_airgap.ps1
+2. unpack_and_offline_build_airgap.ps1
+
+[2] Packing Scripts Start --Options: Internet connect Require when you packing, after then you will get all gradle File
+command on powershell: powershell -ExecutionPolicy Bypass -File .\pack_offline_bundle_airgap.ps1
+
+[3] UnPacking Scripts Start --Options: The JPA Spring boot Project All gradle, gradle cache File, Build File etc (Check using .\gradlew.bat bootRun --offline)
+command on powershell: powershell -ExecutionPolicy Bypass -File .\unpack_and_offline_build_airgap.ps1 .\kamco-dabeeo-backoffice_offline_bundle_20260121_145830.tar.gz (The tar File name have to be changed)
+
+
+PS. You can check the ALL Gradle Backup File location Users/d-pn-0071/Desktop/lala/kamco-dabeeo-backoffice/gradle/win/kamco-dabeeo-backoffice_gradle.tar.gz
