I am having a multi module java and spring boot projects, Under one of my java module ("workflow") where a class is annotated as @Component and this module is refereed in another project which is a Spring boot application using componentScan. If I use progaurd to ofuscate only my java module with appropriate progaurd config. My spring boot application("server") is not able to find that Component bean. I have tried almost all types of progaurd configuration, but keep getting error on startup: Field mapperFactory in ...Converter required a bean of type '...MapperFactory' that could not be found.
