scalapb

jvm_plugins

A list of JVM-based protoc plugins to invoke when generating Scala code from protobuf files. The format for each plugin specifier is NAME=ARTIFACT where NAME is the name of the plugin and ARTIFACT is either the address of a jvm_artifact target or the colon-separated Maven coordinate for the plugin's jar artifact.

For example, to invoke the fs2-grpc protoc plugin, the following option would work: --scalapb-jvm-plugins=fs2=org.typelevel:fs2-grpc-codegen_2.12:2.3.1. (Note: you would also need to set --scalapb-runtime-dependencies appropriately to include the applicable runtime libraries for your chosen protoc plugins.)

version

Version string for the tool. This is available for substitution in the [scalapb].artifacts option by including the string {version}.

artifacts

[
  "com.thesamet.scalapb:scalapbc_2.13:{version}"
]

Artifact requirements for this tool using specified as either the address of a jvm_artifact target or, alternatively, as a colon-separated Maven coordinates (e.g., group:name:version). For Maven coordinates, the string {version} version will be substituted with the value of the [scalapb].version option.

lockfile

Path to a lockfile used for installing the tool.

Set to the string <default> to use a lockfile provided by Pants, so long as you have not changed the --version option. See https://github.com/pantsbuild/pants/blob/release_2.12.1/src/python/pants/backend/codegen/protobuf/scala/scalapbc.default.lockfile.txt for the default lockfile contents.

To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants jvm-generate-lockfiles --resolve=scalapb.
