If using interactive sbt console, version only gets regenerated on reload

[lukens]

I tend to work in an interactive sbt console, however, this does not regenerate the version number unless you reload.

Is there a way to have these regenerated whenever a task is run?

No :(. version in sbt is a "Setting" which means it's only generated on load/reload.

I recommend making a release script which will ensure a reload/cleaned project.

commands += Command.command("release") { state =>
   "reload" :: "test" :: "publishSigned" :: state
}

Thanks, I will look at doing something like that.

I would love to have this automatically be updated too.

In the meantime, instead of using git to directly tag the version, I use sbt to tag and refresh the project. This way sbt will grab then grab the most recent version.

commands += Command.single("tag"){case (state,versionTag) => 
   println(s"Commiting a git annotated tag of v$versionTag, and refreshing the project ")
   s"git tag -a -m v$versionTag v$versionTag" :: "reload" ::  state
}

Then using the interactive sbt console to make a tag keeps sbt in sync for future commands:

> tag 0.1.0

However, the version is still not refreshed for local changes until a new tag is made. In this case, a release command that includes the refresh command as suggested by @jsuereth may be better.

The following commands, which override the default task, work well for me.

Command.command("package") {
    state => {
      println("==== Reload & package ====")
      "reload" :: "compile:package" :: state
    }
  }

Command.command("assembly") {
    state => {
      println("==== Reload & assembly ====")
      "reload" :: "*:assembly" :: state
    }
  }

I would love this too. But version isn't going to become a task.
