How do I accomplish a task that triggers cleanup in subprojects without using aggregation?
I want to make a request cleanAll
that does a task clean
for multiple subprojects. I don't want to use aggregation just for clean
.
We were having problems with the routes of the game assets when we were using submodules.
Well documented how to create a new task, but how can I call the task in a subproject?

Using Jacek Laskowski as an example, I came up with the following plugin, which should be placed in a folder /project
:
import sbt._
import sbt.AutoPlugin
import sbt.Keys._
import sbt.plugins.JvmPlugin
object CleanAllPlugin extends AutoPlugin {
val cleanAll = taskKey[Unit]("Cleans all projects in a build, regardless of dependencies")
override def requires = JvmPlugin
override def projectSettings = Seq(
cleanAllTask
)
def cleanAllTask = cleanAll := Def.taskDyn {
val allProjects = ScopeFilter(inAnyProject)
clean.all(allProjects)
}.value
}
The plugin can now be added to the root project for use:
val main = Project("root", file("."))
.enablePlugins(CleanAllPlugin)
It can be executed in SBT by calling: cleanAll

Use the following build.sbt
:
val selectDeps = ScopeFilter(inDependencies(ThisProject))
clean in Compile := clean.all(selectDeps).value
It is assumed that the file build.sbt
is in the project, which clean
is executed by itself and dependsOn
projects.
If you need it in project/Build.scala
, just add the following:
val selectDeps = ScopeFilter(inDependencies(ThisProject))
val cleanInSubprojects = Seq(
clean in Compile := clean.all(selectDeps).value
)
and add cleanInSubprojects
to the settings of each project:
// definition of a project goes here
.settings(cleanInSubprojects: _*)
