如何通过需要与mongoDB对话的Java运行水壶工作？

Question

我一直试图通过Java运行水壶任务。该作业正在运行，但是参数也通过代码传递给该作业，但它不会与mongoDB通讯。

这里有代码，我正在尝试使用。

Properties prop = new Properties();
InputStream input = null;
input = getClass().getClassLoader().getResourceAsStream("config.properties");
            prop.load(input);
            String KettleJob = prop.getProperty("Kettle_Job_Param");//Job file path that needs to be executed



            Repository repository = null; //Checking for repository
            getProjectUnits.updateProjectStatus(User_ID, Project_ID, "4");
            try {
                KettleEnvironment.init();
            }catch (Exception e) {
                System.out.println("Kettle Error");
            }

            JobMeta jobmeta=new JobMeta(KettleJob,repository);
            Job job=new Job(repository, jobmeta);

            /* Doing the basic initialization for executing a job */
            job.initializeVariablesFrom(null);
            job.getJobMeta().setInternalKettleVariables(job);
            job.copyParametersFrom(job.getJobMeta());

            /* Setting the Parameters to the job object
             * @Parameter Names: PARAM_ID and PARAM_NAME*/

            job.setParameterValue("User_ID", User_ID);
            job.setParameterValue("Project_ID", Project_ID);
            //job.setLogLevel(LogLevel.MINIMAL);
            //job.setLogLevel(LogLevel.ERROR);
            //job.setLogLevel(LogLevel.DEBUG);
            job.setLogLevel(LogLevel.ROWLEVEL);

            /*Activating the Parameters and executing the Job   */
            job.activateParameters();

            job.shareVariablesWith(jobmeta);

            job.execute(0, null);
            job.waitUntilFinished();

            if(job.getErrors()>0){
                getProjectUnits.updateProjectStatus(User_ID, Project_ID, "5");
                return Response.status(Status.INTERNAL_SERVER_ERROR).entity("Error while initiating process.").build();
            }
            job.setFinished(true);
            getProjectUnits.updateProjectStatus(User_ID, Project_ID, "6");
            BasicDBObject status = new BasicDBObject();
            status.put("Status", 1);

            return Response.ok().entity(status.toString()).build();

与Maven的依赖关系如下：

它没有显示任何错误，但是由作业完成的更改未反映在mongoDB中。
