Currently includeInApplicationXml configuration option is available only for jarModule: https://maven.apache.org/plugins/maven-ear-plugin/modules.html#jarModule
We need to use it also for another module (in our case it is webModule). I think it will be fine to enable this option for all modules (ejb, web, ...). The motivation is to enable specific ear to be built with modules by default not described in application.xml. Person responsible for deploying will add modules to application.xml based on current case.
