+#gCube Dependency Walker Pipeline
+Given a Jenkins project P:
+ - navigate the maven modules built by P
+ - return the list of projects that have modules depend on each maven module in P
+ 
+Given a maven module's coordinates:
+ - return the list of Jenkins projects that have modules depend on the input maven module
+
+
+## Requirements
+* [Jenkins](https://jenkins.io/) ver. 2.164.2 or newer
+* [Pipeline plugin](https://wiki.jenkins.io/display/JENKINS/Pipeline+Plugin)
+* [Pipeline: Maven](https://plugins.jenkins.io/pipeline-maven)
+* [Pipeline: Basic Steps](https://plugins.jenkins.io/workflow-basic-steps) 
+* [Pipeline: Dependency Walker](https://plugins.jenkins.io/pipeline-dependency-walker/) 
+* [NodeLabelParameter](https://plugins.jenkins.io/nodelabelparameter) (to allow to dynamically select the node on which a job should be executed)
