Separate "lib" project when creating new Gradle project

This morning I installed an update to Buildship and created a new Gradle project. That created two projects under Package Explorer, which it has never done before. I had the project with the name I created plus a project “lib”. The Properties for the lib project show that it’s a sub-folder on the actual project.

I don’t see anything in the patch notes that would explain this strange new behavior. Does anyone know what causes this and how I can fix it?

Thanks
