Version Matrix


Put all the documentation for a project in one place. Defaults to an alldocs folder under project root. Suitable for distribution of an alldocs for an alljar (aka uberjar). This will include all dependencies and all compiler version targets. The result is a large but complete set of documentation.

Add to project/plugins.sbt:

addSbtPlugin("com.glngn" % "sbt-alldocs" % "0.2.2")

At sbt prompt:

sbt> update
sbt> allDocs

Open in web browser: alldocs/index.html.

This plugin requires sbt 1.2.0+

This adds a command allDocs which:

  1. Collects all documentation artifacts for dependencies. This is all dependencies minus those in allDocsExclusions.
  2. Expands all documentation artifacts into allDocsTargetDir. Which defaults to alldocs.
  3. Generates all documentation for all projects. These are copied under allDocsTargetDir.
  4. Finally, generates an index.html in allDocsTargetDir that is an index of all the collected documentation.


Note: the options refer to name and this is ill-defined. This is exactly the link text. Easiest to generate all docs then look at link text to determine name.

  • allDocsExclusions - Set of strings of the name for the document artifact to exclude.
  • allDocsRenames - Map of names to text. This is applied after exclusions.
  • allDocsTargetDir - Directory relative to root to output. Defaults to alldocs.
  • allDocsSections - Map of regex to (priority, section text).


allDocsSections := Seq(
    "akka-.*" -> (20, "Akka"),
    "log4j-.*" -> (30, "Logging (Log4j 2)"),
    "slf4j-.*" -> (30, "Logging (Log4j 2)"),
    "scala-.*" -> (10, "Scala Standard Libraries"),
    "scalaz-.*" -> (15, "Scalaz Libraries"),
    ".*" -> (999, "Other Included Libraries")


Run test for regular unit tests.

Run scripted for sbt script tests.

This command may take a while. All dependencies for all compiler targets is, even on small projects, a large number of files to decompress from jar files. In particular, I've found windows to be exceptionally slow at this. The recommended pattern is for the organizations CI/CD to deploy this artifact to a local server.

Failure to generate project documentation does not result in the command failing. The project documentation will be, however, missing from the index. The first part is intentional. The second part contains a bug. The goal is to support fetching the docs of new dependencies before the project even compiles. The issue is any exist project docs should still be included in the index.
