As the native-image tool takes a JAR file as an input, it is recommended to package native-image.properties in META-INF/native-image/<unique-application-identifier> within the JAR file. A unique application identifier is used to avoid any collision of resources. These paths have to be unique, as they will be configured on CLASSPATH.
