How to resolve java.lang.module.ResolutionException in JDK9

I am on build 109 of JDK9 with the Jigsaw build.

I am trying a hello-world type of example just to get started with JDK9 modular development. When I launch the application, I am getting the following RuntimeException (I am providing the java launcher command as well):

C:\JDK9Tryouts\HelloWorld1>java -modulepath mods -m hello.world1\hello.world1.HelloWorld1

Error occurred during initialization of VM
java.lang.module.ResolutionException: Module hello.world1\hello.world1.HelloWorl

As you can see I have set the -modulepath to refer to the directory which contains user defined modules.

What should I target in order to debug this.

Looks like you have the wrong slash /, I assume you want:

java -mp mods -m hello.world1/hello.world1.HelloWorld1
