Accessing value with same named parent

Question

Here I have some JSON generated by Jenkins, I would like to access the value Started by user XXX in the below JSON with GSON.

Although as you can see there are two causes in the actions array. Although sometimes there is only one (In which case just return that one).

Question: How can I access the first causes only OR even better conjoin them both so I could access it like Started by user XXX - Rebuilds build #2

I cannot change the JSON unfortunately.

Edit* I understand the title is probably not the best although I cannot think of another way of phrasing it so if anyone can think of a better one I would be much obliged.

{
  "jobs" : [
    {
      "name" : "Test Build",
      "url" : "URL",
      "lastBuild" : {
        "actions" : [
          {
            "causes" : [
              {
                "shortDescription" : "Started by user XXX"
              }
            ]
          },
          {
            "causes" : [
              {
                "shortDescription" : "Rebuilds build #2"
              }
            ]
          },
          {
            "parameters" : [
              {
                "name" : "ENVIRONMENT",
                "value" : "PROD"
              },
              {
                "name" : "RELEASE"
              }
            ]
          }
        ],
        "building" : false,
        "duration" : 126580,
        "estimatedDuration" : 74509,
        "number" : 3,
        "timestamp" : 1445261252000,
        "url" : "URL",
        "builtOn" : "D-slave"
      }
    },

Try with expression below. 0 index will give you first element.

jobs[0].lastBuild.actions[0].causes

This will give you

[
   [
      {
         "shortDescription":"Started by user XXX"
      }
   ]
]

Change the expression wherever necessary.

Java code for all classes below - based on your json format.

So you need something like jenkinjobs.jobs(0).getActions(0).

    public class Jenkinjobs
    {
        private Jobs[] jobs;

        public Jobs[] getJobs ()
        {
            return jobs;
        }

        public void setJobs (Jobs[] jobs)
        {
            this.jobs = jobs;
        }

        @Override
        public String toString()
        {
            return "ClassPojo [jobs = "+jobs+"]";
        }
    }


public class Jobs
{
    private LastBuild lastBuild;

    private String name;

    private String url;

    public LastBuild getLastBuild ()
    {
        return lastBuild;
    }

    public void setLastBuild (LastBuild lastBuild)
    {
        this.lastBuild = lastBuild;
    }

    public String getName ()
    {
        return name;
    }

    public void setName (String name)
    {
        this.name = name;
    }

    public String getUrl ()
    {
        return url;
    }

    public void setUrl (String url)
    {
        this.url = url;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [lastBuild = "+lastBuild+", name = "+name+", url = "+url+"]";
    }
}


public class LastBuild

    private String timestamp;

    public String getTimestamp ()
    {
        return timestamp;
    }

    public void setTimestamp (String timestamp)
    {
        this.timestamp = timestamp;
    }

    public String getEstimatedDuration ()
    {
        return estimatedDuration;
    }

    public void setEstimatedDuration (String estimatedDuration)
    {
        this.estimatedDuration = estimatedDuration;
    }

    public String getDuration ()
    {
        return duration;
    }

    public void setDuration (String duration)
    {
        this.duration = duration;
    }

    public String getBuilding ()
    {
        return building;
    }

    public void setBuilding (String building)
    {
        this.building = building;
    }

    public String getNumber ()
    {
        return number;
    }

    public void setNumber (String number)
    {
        this.number = number;
    }

    public String getBuiltOn ()
    {

    {
        return actions;
    }

    public void setActions (Actions[] actions)
    {
        this.actions = actions;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [timestamp = "+timestamp+", estimatedDuration = "+estimatedDuration+", duration = "+duration+", building = "+building+", number = "+number+", builtOn = "+builtOn+", url = "+url+", actions = "+actions+"]";
    }
}

public class Parameters
{
    private String name;

    private String value;

    public String getName ()
    {
        return name;
