Building Jigsaw on Windows

Building Jigsaw on Windows is the same as building OpenJDK8 except that the URL to use in step 13 to get the root source is http://hg.openjdk.java.net/jigsaw/jigsaw/

hg clone http://hg.openjdk.java.net/jigsaw/jigsaw/

Post build define a JIG enviroment variable to prefix your java command:

 set JIG=C:\dev\jigsaw\build\windows-x86_64-normal-server-release\images\jdk-module-image

A few commands:
List the modules in the JDK system library:

 %JIG%/bin/jmod list

Launch a modular java application:

%JIG%/bin/java -m jdk.jconsole
