The error you are getting means that the class you are specifiying is not found on the classpath.

This could be eiether because you have mispelled the class name or the class itself or the jar file containing it is not on the classpath.

Since you are usging ./knowledge-generator.jar this means that the jar file is located on the same directory from where you are executing the command (current wurking directory). make sure the jar file is there (execute the command ls) and that the jar file contains the class you are trying to use as entry point to your java application

Add the full path of the jar that you're adding to your classpath. For example:

java -cp C:/myprog/knowledge-generator.jar com.abc.credit.data.knowledgegenerator.KnowledgeGenerator --inputFiles `pwd`/CIA_CP_LDM.ttl --outputFolder `pwd`
