Answer 1

You are trying to generate partner.jar using WSDL file and you are using "force-wsc-36.1.1.jar" (File as Web Service Connector).
As of WSC-36 connector required an additional framework to generate "partner.jar" call "StringTemplate engine framework".
Download latest "StringTemplate binary" jar file using below link: String Template jar file
Put that String template jar, wsc jar and WSDL files in one location.
Open CMD
Go to the directory where you put your all files.
Fire below command to generate a partner.jar file.
java -classpath force-wsc-36.1.1.jar;ST-4.0.8.jar com.sforce.ws.tools.wsdlc partner.wsdl partner.jar
Syntax: Java -classpath [WSC jar file];[String template jar file] com.sforce.ws.tools.wsdlc [Partner.wsdl file] [Ouput file name with .jar extation]

Answer 2

Create a folder named wsdl in your C:\ drive and copy following jars in to it:
force-wsc-54.0.0.jar ST-4.3.1.jar rhino-1.7.14.jar antlr-4.0-complete.jar
Open cmd and run:
java -classpath C:\wsdl\force-wsc-54.0.0.jar;C:\wsdl\ST-4.3.1.jar;C:\wsdl\rhino-1.7.14.jar;C:\wsdl\antlr-4.0-complete.jar com.sforce.ws.tools.wsdlc partner.wsdl.xml C:\wsdl\sf-partner.jar
Note: C:\wsdl\sf-partner.jar is a generated .jar stub file
