Windows Prerequisites

Install the Java Development Kit

GeoFIS build needs the Java Development Kit (JDK) to be installed (version 1.8 or greater). Note that the Java Runtime Environment (JRE) is not sufficient, you will need the JDK.
To check if you have the JDK installed, type this on the Windows terminal (Winkey + R then type cmd):

javac -version

If you do not have the JDK installed, download and install the Java SE JDK (SE = Standard Edition).

Setting the JAVA_HOME

set JAVA_HOME system environment variable to the location of your JDK, e.g. C:\Program Files\Java\jdk1.8.0_80

Install Apache Maven

Download the latest Maven binary zip archive and follow Installation Instructions.

Install SWIG

Download the latest swigwin Windows prebuilt executable and unzip to the directory you wish to install SWIG.
Add the unpacked ‘bin’ directory to Windows System Path.
Open a new Windows command-line and run swig -version to verify that it is correctly installed.
