D:\PMT_LandingPage\nbproject\jfx-impl.xml:3725: The following error occurred while executing this line:

Either open the project in the IDE and setup the Platform with the same name or add it manually.
For example like this:
ant -Duser.properties.file=<path_to_property_file> jar (where you put the property "platforms.default_platform.home" in a .properties file)
