A plugin for sbt 0.13.x and 1.x that generates code based on a JFlex specification.

It is based on the sbt-antlr plugin.

This project is (C)opyright 2011 Steffen Fritzsche and (C)opyright 2013—2018 Hanns Holger Rutz, and published under the Apache 2.0 License.

Add a dependency to the plugin in ./project/plugins.sbt:

addSbtPlugin("de.sciss" % "sbt-jflex" % "0.4.0")

Place your JFlex grammar files in src/main/jflex and they will be included in your next build. Note, sbt-jflex generates the source code only once as long as your grammar file did not change; it does not re-generate the java source files.

Include the following line in build.sbt (sbt 1.x) to import the JFlex plugin settings:

SbtJFlexPlugin.jflexSettings

Note that cross-sbt plugin compilation and publishing requires ^ magic cookie. So sbt ^compile for example to compile both for sbt 0.13.x and sbt 1.x.
