Demo Application demonstrating ProGuard applied to a Spring Boot application
Building
./gradlew clean proguard --info
Spring Boot applications contain a BOOT-INF folder which contains the application class files and library jars. We must first extract the program classes, then apply ProGuard to them and finally repackage the application.
