> The plugin execution configuration may interfere across maven modules included in a build in case a plugin extension provides a default configuration.
> Because the custom plugin configuration defined in the maven modules is merged to the plugin execution configuration and the merged configuration is re-used during building the other included maven modules, so the other maven modules may be build using the invalid configuration.
