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?

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 integrationbut 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
