Java Pentaho Exception MongoDB

问题

I have designed a transformation in Pentaho Data Integration ui tool and wrote a java code to execute the transformation. I followed below resources link as it is,

try {
      /**
       * Initialize the Kettle Enviornment
       */
      KettleEnvironment.init();

      /**
       * Create a trans object to properly assign the ktr metadata.
       * 
       * @filedb: The ktr file path to be executed.
       * 
       */
      TransMeta metadata = new TransMeta("Districts.ktr");
      Trans trans = new Trans(metadata);

      // Execute the transformation
      trans.execute(null);
      trans.waitUntilFinished();

      // checking for errors
      if (trans.getErrors() > 0) {
          System.out.println("Erroruting Transformation");
      }

  } catch (KettleException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
  }

My transformation has Mongo DB input and then insert in to postgresql. With pentaho version 5.0.0.1 it throws following error

org.pentaho.di.core.exception.KettleMissingPluginsException: 

Missing plugins found while loading a transformation

Step : MongoDbInput at org.pentaho.di.trans.TransMeta.loadXML(TransMeta.java:2931) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2813) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2774) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2759) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2744) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2718) at org.pentaho.di.trans.TransMeta.(TransMeta.java:2690) at org.kettle.test.Execute.main(Execute.java:72)

What could be the reason behind this?

Thank you in advance

Added kettle.properties file the plugin folder location

KETTLE_PLUGIN_BASE_FOLDERS = /Users/dir/kettel/Plugin
