I have application that has multiple module (about 20 modules). These modules are libraries except 2. One of the module is wrapper that specifies which module to use. There is also module that has main class that starts gui. I migrated project to maven. So I am now using the recommended project structure. Each module has its own pom.xml and there is parent pom.xml that includes used modules.
I would like to execute the main class using maven plugin. I am not sure, where to put the execution plugin, for it to see all of included modules. By default I was starting the application from the wrapper module that pointed to the main class. There I also told the app what module to use. What is the correct way of the project structure for it to execute as expected?
I tried this plugin in this configuration in the wrapper module. But it failed to see other modules.
