I am attempting to complete the aforementioned trailhead step on a Windows 10 machine. When I attempt to test the setup via sfdx force:auth:jwt:grant, I get the following error:

This org appears to have a problem with its OAuth configuration. Reason: invalid_grant - user hasn't approved this consumer

When it gives the error, SFDX provides a list of possible issues to check for. I have done so repeatedly. I have gone through the Trailhead step backwards and forwards. Every other part seems to work just fine. This part does not. Unfortuntely the Google results haven't really been all that helpful, so now I turn to you oh great and powerful forum. What do you say?

I am having the enterprise.wsdl file and i am trying to create a jar file using command 

 

java -classpath wsc-20.jar com.sforce.ws.tools.wsdlc enterprise.wsdl enterprise.jar

 

but getting an error "Error: Unable to find compiler. Make sure that tools.jar is in your classpath:

java.lang.ClassNotFoundException: com/sun/tools/javac/Main.class"

 

can anyone help me..............

 

thank you.......................
