The User Guide, in table 28.2, 28.3 and 28.4 implies that the generated IntelliJ meta files will be named based on projectDir/<project.name>. However, I tried altering a project's name in settings.gradle and that name was not used by the IdeaPlugin.

The problem is that i have a multi-project structure where the root directory is named hibernate-core and a sub-project is in a directory hibernate-core/hibernate-core. Trying to create an IntelliJ project for this creates 2 files named hibernate-core.iml. IntelliJ takes the name of the module based on the name of the iml file (it would seem), so it has problems with this.
