sbt-avro
Overview
sbt-avro is a plugin for sbt-0.13 for generating the Java sources for Avro schemas and protocols. It tries to be clever in compiling schemas with referenced types before dependent ones.
Usage
Install the plugin
Add the plugin according to the sbt documentation.
For instance, add the following lines to the file project/plugins.sbt in your
project directory:
addSbtPlugin("com.cavorite" % "sbt-avro-1-8" % "1.1.3")
Scope
All settings and tasks are in the avro scope. If you want to execute the
generate task directly, just run avro:generate.
