在Java上运行PDI Kettle-Mongodb步骤缺少插件 [英] Running PDI Kettle on Java - Mongodb Step Missing Plugins

问题描述

我正在尝试执行一个转换，其中包括来自Java应用程序的mongodb输入步骤，但此消息始终导致错误:

I am trying to run a transformation which includes mongodb input step from a java app but always resulting error with this message:

org.pentaho.di.core.exception.KettleMissingPluginsException: 
Missing plugins found while loading a transformation

Step : MongoDbInput

我从此线程中找到了一些相关的答案: 生气的org.pentaho.di.core.exception.KettleMissingPluginsException在Step中:JmsOutput为什么?

I've found some related answer from this thread: Angry org.pentaho.di.core.exception.KettleMissingPluginsException in Step : JmsOutput Why?

将插件移动到应用程序文件夹的根路径，我这样做了，但仍然出现错误，并带有不同的消息:

which is to move the plugins to the root path of the applications folder, I did and but still resulting error with different message :

Exception in thread "main" java.lang.AbstractMethodError

我试图传递一个参数:

-DKETTLE_PLUGIN_BASE_FOLDERS=/home/razza/PentahoCE/pdi-ce-5.1.0/data-integration/plugins

就像在该线程上所建议的那样: Pentaho MongoDBInput Java集成 但仍然不能解决我的问题

just as suggested on this thread: Pentaho MongoDBInput Java integration but still didn't solve my problem

我已经通过kitchen.sh命令检查了运行我的kjb文件，以防万一，并且运行正常，没有任何问题.

I have checked running my kjb files via kitchen.sh command just in case, and it was running fine without any problems.

有人可以帮我看看我做错了什么吗? 谢谢

Can anyone help showing me which part did I do wrong? Thanks

推荐答案

请参见如果这是您所做的，那么它应该可以工作.您确定安装正确吗?您设置了OPT变量

If this is what you did it should work. Are you sure you installed the plugin correctly? You set the OPT variable

export OPT="-verbose:class"

当您运行spoon.sh时，它将向您显示所有已加载的类.您可以验证它是否从插件中找到了类.

When you run spoon.sh then this will show you all loaded classes. You could verify if it finds the classes from the plugin.

您可以使用jar实用程序在插件中找到类，例如:

You can find the classes in the plugin using the jar utility, eg:

jar tf ${plugin_folder}/mongodb.jar
