How to extract data from build.sbt on the command line

Question

I would like to receive data of type version, packageName in Dockerand anyway. I need my CI to label the docker image for future use. Thus, is it possible to get values ​​like with maven mvn --batch-mode -f pom.xml help:evaluate -Dexpression=project.version. Thank you for your help.

So, my build.sbt contains several projects, and now I'm trying to use sbt projects, sbt inspectfrom sbt, to check the assembly , but so far no luck.

I managed to get the key values ​​from the project, but now I have a problem with packageName in Docker. I do this with help sbt [project_name]/[key], but for packageName in DockerI got:

sbt projectName/packageName in Docker
[error] Not a valid command: in
[error] Expected 'info'
[error] Not a valid project ID: in
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: in
[error] in
[error]   ^

This is part of build.sbt:

lazy val `name` = project
  .in(file("name"))
  .dependsOn(`name-dep`)
  .settings(defaults)
  .settings(
    packageName in Docker := "project/name",
    version := "3.1.0-SNAPSHOT",
    dockerExposedPorts := Seq(8080),
    dockerCommands ++= Seq(
      Cmd("ENTRYPOINT",
        s"bin/${executableScriptName.value}",
        "-l", "tcp://0.0.0.0:8081",
        "-e", "${EXTERNAL_URL}",
        "-c", "${CONNECTOR_URL}")
    ),

For the version I use:

sbt name/version
[info] Loading project definition from /home/jenkins/.jenkins/workspace/project
[info] Set current project to root (in build file:/home/jenkins/.jenkins/workspace/)
[info] 3.1.0-SNAPSHOT

but i have problems with packageName in Docker

My decision:

so I managed to get these values ​​with:

# sbt -Dsbt.log.noformat=true name/packageName | sed -n 3p | cut -d " " -f 2
name

( project/), , , CI script.

# sbt -Dsbt.log.noformat=true name/version | sed -n 3p | cut -d " " -f 2
3.1.0-SNAPSHOT

- , , .

, sbt ASCII , , sbt -Dsbt.log.noformat=true, CI ENV, .
