A project is imported or created according the default Maven integration settings.
Further, you can configure the current project in the Maven Integration
dialog invoked by the button.
These settings are used on project reopening and synchronizing.
Besides settings that apply to the current project, IntelliJ IDEA provides the possibility to configure the
default settings, which apply to all newly created or imported projects. These settings are available in the
Maven Integration: Default settings dialog, invoked by the
button, or in the Template Project settings.
