chetanmeh opened a new pull request #4110: Exclude unused transitive dependencies
URL: https://github.com/apache/incubator-openwhisk/pull/4110
 
 
   Excludes some of the transitive dependencies which are not used at runtime saving 14MB in disk space. 
   
   ## Description
   
   Some of the dependencies can be excluded from build as they would not be used. The dependencies were analyzed via following command
   
   ```
   ./gradlew :core:controller:dependencies --configuration runtime
   ```
