 - `githubWorkflowBuildPreamble` : `Seq[WorkflowStep]` – Contains a list of steps which will be inserted into the `build` job in the **ci.yml** workflow *after* setup but *before* the `sbt test` invocation. Defaults to empty.
 - `githubWorkflowBuildPostamble` : `Seq[WorkflowStep]` – Similar to the `Preamble` variant, this contains a list of steps which will be added to the `build` job *after* the `sbt test` invocation but before cleanup. Defaults to empty.
 - `githubWorkflowBuild` : `Seq[WorkflowStep]` – The steps which invoke sbt (or whatever else you want) to build and test your project. This defaults to just `[sbt test]`, but can be overridden to anything. For example, sbt plugin projects probably want to redefine this to be `Seq(WorkflowStep.Sbt(List("test", "scripted")))`, which would run the `test` and `scripted` sbt tasks, in order. Note that all uses of `WorkflowStep.Sbt` are compiled using the configured `githubWorkflowSbtCommand` invocation, and properly configured with respect to the build matrix-selected Scala version.
-- `githubWorkflowJavaVersions` : `Seq[String]` – A list of Java versions, using [Jabba](https://github.com/shyiko/jabba) syntax, which will be used to `build` your project. Note that the `publish` job will always run under the very first of these versions. Defaults to `[adopt@1.8]`.
+- `githubWorkflowJavaVersions` : `Seq[JavaSpec]` – A list of Java versions to be used for the build job. The publish job will use the *first* of these versions. Defaults to `JavaSpec.temurin("11")`).
 - `githubWorkflowScalaVersions` : `Seq[String]` – A list of Scala versions which will be used to `build` your project. Defaults to `crossScalaVersions` in `build`, and simply `scalaVersion` in `publish`.
 - `githubWorkflowOSes` : `Seq[String]` – A list of operating systems, which will be ultimately passed to [the `runs-on:` directive](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idruns-on), on which to `build` your project. Defaults to `ubuntu-latest`. Note that, regardless of the value of this setting, only `ubuntu-latest` will be used for the `publish` job. This setting only affects `build`.
 - `githubWorkflowBuildRunsOnExtraLabels` : `Seq[String]` - A list of additional runs-on labels, which will be combined with the matrix.os from `githubWorkflowOSes` above allowing for singling out more specific runners.
