我在 Pentaho Data Integration ui 工具中设计了一个转换，并编写了一个 java 代码来执行转换。我照原样按照以下资源链接进行操作，

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();
  }

我的转换有 Mongo DB 输入，然后插入到 postgresql。使用 pentaho 版本 5.0.0.1 它会引发以下错误

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

加载转换时发现缺少插件

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

这背后的原因可能是什么？

先感谢您

添加kettle.properties文件插件文件夹位置

KETTLE_PLUGIN_BASE_FOLDERS = /Users/dir/kettel/Plugin
