[gradle] Intellij Can Not Gradle Build Project Oline Mode In Closed Network

1. Issue
   • When I try to build project made by gradle wrapper in closed network, IntelliJ can’t do it.
   • Environemnt
     • Closed network (Bank site: can’t access internet)
     • Manage dependency files by Nexus solution. Gradle has to connect to Nexus repositories url.
     • For using connect Nexus repositories, Intelli J is set online mode.
2. Reason
   • Intelli J needs the gradle-src.zip for checking version before building project.
     • If local gradle doesn’t have -src files, Intelli J try to download them from internet.
   • After checking version, Intelli J use gradle-bin.zip for building project
   • In closed network, you have to use gradle-all.zip for success gradle build by upper process.
3. Solution
   • Place gradle-all.zip file in distributionPath
   • Set gradle-wrapper.properties like below

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
# for online
# distributionUrl=https\://services.gradle.org/distributions/gradle-6.9.2-bin.zip
# for offline
#distributionUrl=dists/gradle-6.9.2-bin.zip
distributionUrl=dists/gradle-6.9.2-all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
