- Create a C:\dev\ directory 
 - Download and install Visual Studio 2013 Community 
- Download (it may be faster to download the ISO)
 - Install 
- uncheck all the options
 - or download AdminDeployment.xml to C:\dev\temp then start the installation with:
vs_community.exe /AdminFile C:\dev\temp\AdminDeployment.xml
 
 - Add the path to MSBuild to the PATH environement variable (required to build Freetype):
C:\Program Files (x86)\MSBuild\12.0\Bin
 
 - Download and install the Mercurial for Windows
 - Download and install Java 8 (for OpenJDK)
 - Download and install JDK 9 b109
 - Move C:\Program Files\Java\jdk-9\lib\jfxrt.jar out of the way (rename it jfxrt.jar.disabled for instance)
 - Download and install Babun, then use its package manager to install zip :
pact install zip
 - Download Freetype source (2.6.2) and extract to C:\dev\freetype-2.6.2
 - Download Gradle 2.11 and extract it into C:\dev
 - Get Jake's source
In the Babun console:
cd /cygdrive/c/dev hg clone http://hg.openjdk.java.net/jigsaw/jakecd /cygdrive/c/dev/jake ./get_source.sh - Get OpenJFX Jigsaw prototype source
In the Babun console:cd /cygdrive/c/dev hg clone http://hg.openjdk.java.net/openjfx/sandbox-9-jake/rt/ jfx-jake
 - Build OpenJFX
In the 'DOS' console:cd C:\dev\jfx-jake
set GRADLE_HOME=C:\dev\gradle-2.11
set JAVA_HOME=C:\Program Files\Java\jdk-9
set PATH=%PATH%;%JAVA_HOME%\bin;%GRADLE_HOME%\bin;%USERPROFILE%\.babun\cygwin\bin
gradle - Run the auto-conf script for OpenJDK
In the Babun console:cd /cygdrive/c/dev/jake
bash configure --with-freetype-src=/cygdrive/c/dev/freetype-2.6.2 --with-import-modules=/cygdrive/c/dev/jfx-jake/build/modular-sdk - Time for cooking
make images
 - Once done, open a new 'DOS' console and navigate to
cd C:\dev\jake\build\windows-x86_64-normal-server-release\images\jdk
check that java runs:bin\java -version
or for something a bit more visual:bin\jconsole
 -  To check JavaFX, 
in the 'DOS' console compile the sample apps:cd C:\dev\jfx-jake
set GRADLE_HOME=C:\dev\gradle-2.11
set JAVA_HOME=C:\Program Files\Java\jdk-9
set PATH=%PATH%;%JAVA_HOME%\bin;%GRADLE_HOME%\bin;%USERPROFILE%\.babun\cygwin\bin
set JIGSAW_HOME=C:\dev\jake\build\windows-x86_64-normal-server-release\images\jdk
gradle apps
then launch:%JIGSAW_HOME%\bin\java -jar C:\dev\jfx-jake\apps\samples\Ensemble8\dist\Ensemble8.jar
 - hack!
