               https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#AppendingTransformer

               Some jars contain additional resources (such as properties files) that have the
               same file name. To avoid overwriting, you can opt to merge them by appending
               their content into one file.

               For example the spring-context-5.0.7.RELEASE.jar and spring-aop-5.0.7.RELEASE.jar
               both have spring.handlers.

               The spring aop jar‘s content is
               http://www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler

               The spring context jar‘s content is
               http://www.springframework.org/schema/context=org.springframework.context.config.ContextNamespaceHandler
               http://www.springframework.org/schema/jee=org.springframework.ejb.config.JeeNamespaceHandler
               http://www.springframework.org/schema/lang=org.springframework.scripting.config.LangNamespaceHandler
               http://www.springframework.org/schema/task=org.springframework.scheduling.config.TaskNamespaceHandler
               http://www.springframework.org/schema/cache=org.springframework.cache.config.CacheNamespaceHandler

               With the AppendingTransformer they can be consolidated into one spring.handlers.

               Without AppendingTransformer, the former jar‘s handlers will be overwritten.
               In that case, some flow/topology submission will fail.
