You Need To Install JRE (Java Runtime Environment) Not Open JDK !
Download It From http://www.filehippo.com/download_jre/ (Windows)
You Need To Install 1.7.x Versions
After Installing JRE Just Run windows-run.bat
Still In Development !
it's based on the sources of Ipk Packager and jpkg-webos but with so many changes
windows-run.bat is for Windows but as you know you can run a jar file in any operating system (Mac OS , linux , ...) because it's Java
i did compile it with Java 7 so you need JRE 1.7.x
enjoy creating ipk files
"any", "arm" and "armv7a-vfp" architectures added
"priority", "section", "conflicts", "replaces", "source", "homepage", "license", "oe" fields added
unneeded settings removed
faster than before and more compatible with enigma2 packages
full size by default, layout fixes/updates
fix "-" in version, now you can have -r1 for example
clean and rebuild using JDK 7u45
