In my build.sbt I want to know the current target file. Something like this:

val targetFile = ??? // /home/fbaierl/Repos/kcc/scala/com.github.fbaierl/target/scala-2.12/myapplication_2.12-1.2.3-SNAPSHOT.jar

With target.value I only get the directory up until /target. Is there any way to get the full path to the resulting jar?

What you need is the return value of compile:package.

Run sbt "show compile:package" to see that it prints full path to the artifact you are building.

If you just need the path without building the artifact, do sbt "show Compile / packageBin / artifactPath"

In order to use this value in build.sbt, you have to define a task or setting like this

val targetFile = taskKey[File]("shows target file")

targetFile := 
 val path = artifactPath.in(packageBin).in(Compile).value
 //same as val path = (Compile / packageBin / artifactPath).value
 streams.value.log.info(path.toPath.toString)
 path

A value of any task in sbt cannot be directly assigned to a val like val someFile: File. You have to write your custom logic in terms of settings and tasks.

  @IvanStanislavciuc Exactly. Just like you cannot use vals and defs outside of class / object / package-object definitions in ordinary scala code. I assume that this is clear, and don't see any reason to point it out every time. Global structure of SBT's build files is not the topic of the question.
