    This type of task allows to execute a code written in the Groovy script language. The script can be defined in place or using a path to external .groovy file. It is possible to use some variables.

    The basic attribute of this task is a source code of written in Groovy.

    Example of use Groovy script

    This example shows a script which writes a text file describing the finished graph. It shows use of the 'run' variable.

    import com.cloveretl.server.persistent.RunRecord;
    String dir = "/tmp/";
    RunRecord rr = (RunRecord)run        ;
    String fileName = "report"+rr.getId()+"_finished.txt";
    FileWriter fw = new FileWriter(new File(dir+fileName));
    fw.write("Run ID       :"+rr.getId()+"\n");
    fw.write("Graph ID     :"+rr.getGraphId()+"\n");
    fw.write("Sandbox      :"+rr.getSandbox().getName()+"\n");
    fw.write("Start time   :"+rr.getStartTime()+"\n");
    fw.write("Stop time    :"+rr.getStopTime()+"\n");
    fw.write("Duration     :"+rr.getDurationString()+"\n");
    fw.write("Status            :"+rr.getStatus()+"\n");
