Filling the Packager gap - again

[Kustaa Nyholm]

Hi,

I've been struggling with packaging my app on MacOs High Sierra (10.13.6) with OpenJDK 11.0.1


Literally I've put days into this.

Won't bore you will all the details (unless you want) but my latest attempt is based on this 
and hence I'm addressing this list:

https://mail.openjdk.java.net/pipermail/openjfx-dev/2018-September/022500.html

Specifically I downloaded 

http://download2.gluonhq.com/jpackager/11/jdk.packager-osx.zip

and copied:

jpackager -> /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/bin
jdk.packager.jar -> /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/bin


I also have (copied from jdk1.8.0_102):

/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/lib/ant-javafx.jar

The build works in that it produces a working .dmg and .app with correct icons and all '
(in /private/var/folders/p_/pl6_ggsn1l91rhjklbxk__rcs_tcs9/T/fxbundler7020007958604602553/images/EazyCNC-tmp.dmg etc) 
but the build ends with an unspecified failure (unless it is related to the 'already an item with that name.'):

BUILD FAILED

Any suggestions to how to dig this further or anything would be highly appreciated.

I'm pretty sure I've tried all the workarounds and suggestions that google can find.
