How to rename the default project in sbt

Question

I have a multi-project setup using sbt version 0.13.5

My built.sbt looks like:

lazy val common = (project in file("app-common"))....
lazy val models = (project in file("app-common"))....
lazy val services = (project in file("app-common"))....

When I am in sbt, and I type: projects I see:

common
default-d4d83c
models
services

It is such a pain to type the entire default-a2343 (ok I might be stretching the level of pain I feel, but I am hoping it can get a bit better heeh).

1 What is this default project because I am pretty sure I am not defining it anywher

2 How can I rename this?

Answer 1

It seems this is related to this statement from the sbt documentation :

If a project is not defined for the root directory in the build, sbt creates a default one that aggregates all other projects in the build.

which I take to mean that unless you define a project name for the directory ".", one will be generated automatically. This github commit seems relevant, and looks like it is using a hash from the absolute name of the directory. Simply defining project in file(".")... would seem to be the solution.
