When compiling enterprise.wsdl with force-wsc-58.0.0-uber.jar I was getting the following exception:
$ java -classpath force-wsc-58.0.0-uber.jar com.sforce.ws.tools.wsdlc enterprise-58-0.wsdl enterprise-58-0.0.jar
[WSC][wsdlc.main:72]Generating Java files from schema ...
[WSC][wsdlc.main:72]Generated 2724 java files.
Exception in thread "main" java.lang.NullPointerException

To resolve this issue, I pointed to Oracle JDK and that resolved the issue:
$ /c/jdk1-8-0_202/bin/java -classpath force-wsc-58.0.0-uber.jar com.sforce.ws.tools.wsdlc enterprise-58-0.wsdl enterprise-58-0.0.jar
