Sbt: Is there a better way to structure large build.sbt files

Question

Description of the problem: large sbt file

Our current build.sbtcontains 250 lines.

We have two problems:

readability

current approach for grouping data and comments:

// Plugins ///////////////////////////////////////////////////

enablePlugins(DockerPlugin)

// basic configuration : projects ///////////////////////////
name := """projectName"""

lazy val projectName =
 (project in file(".")).....

reuse of logic

We have some configuration logic that we would like to share between different projects.

Question

Is there any way to include other *.sbtfiles? Or do you have a suggestion to solve this problem without resorting to writing the sbt plugin?
