How can I print all the settings in Test configuration for a project build using SBT? - scala

Question

I have a scala-js project, adding a particular library dependency, is affecting the way project test cases are running. Without the library dependency everything's fine, the moment I add them, tests doesn't execute. I want to check all sbt settings, if those are getting affected. Is there any way I can print all settings and check?

BuildStructure.data seems to give access to all the settings by scope. We could access it by defining a custom command printAllTestSettings like so:
def printAllTestSettings = Command.command("printAllTestSettings") { state =>
val structure = Project.extract(state).structure
val testScope =
Scope(
Select(ProjectRef(new File("/home/mario/sandbox/hello-world-scala/"), "root")),
Select(ConfigKey("test")),
Zero,
Zero
)
structure
.data
.keys(testScope)
.foreach(key => println(s"${key.label} = ${structure.data.get(testScope, key).get}"))
state
}
commands ++= Seq(printAllTestSettings)
Here is output snippet:
...
managedSourceDirectories = List(/home/mario/sandbox/hello-world-scala/target/scala-2.12/src_managed/test)
managedResourceDirectories = List(/home/mario/sandbox/hello-world-scala/target/scala-2.12/resource_managed/test)
testLoader = Task((taskDefinitionKey: ScopedKey(Scope(Select(ProjectRef(file:/home/mario/sandbox/hello-world-scala/,root)), Select(ConfigKey(test)), Zero, Zero),testLoader)))
packageBin = Task((taskDefinitionKey: ScopedKey(Scope(Select(ProjectRef(file:/home/mario/sandbox/hello-world-scala/,root)), Select(ConfigKey(test)), Zero, Zero),packageBin)))
