+ The J2SE Platform is not correctly set up.
+ Your active platform is: ${platform.active}, but the corresponding property "platforms.${platform.active}.home" is not found in the project's properties files.
+ 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.${platform.active}.home" in a .properties file)
+ or ant -Dplatforms.${platform.active}.home=<path_to_JDK_home> jar (where no properties file is used)
