Generate sources from IDL

Mu can generate code from a number of different IDL formats:

• message classes, gRPC server and client from Protobuf .proto files (see Generating sources from Protocol Buffers for detailed instructions)
• message classes, gRPC server and client from Avro .avpr or .avdl files (see Generating sources from Avro)

Plugin Installation

Add the following line to project/plugins.sbt:

addSbtPlugin("io.higherkindness" % "sbt-mu-srcgen" % "0.31.1")

And enable the plugin on the appropriate project(s):

enablePlugins(SrcGenPlugin)

How to use the plugin

The plugin will automatically integrate its source generation into your compile process, so the sources are generated before compilation when you run the compile task.

You can also run the sbt task manually. To generate code from Avro IDL files:

sbt muSrcGen

Or for Protobuf:

sbt protocGenerate

Import

If you want to customize the plugin’s configuration, you will need to add this import at the top of your build.sbt:

import higherkindness.mu.rpc.srcgen.Model._

Settings

For an explanation of the plugin’s settings, see the source generation reference.
