scalapb

The ScalaPB protocol buffer compiler (https://scalapb.github.io/).

Backend: pants.backend.experimental.codegen.protobuf.scala

Config section: [scalapb]

Basic options​

jvm_plugins​

--scalapb-jvm-plugins="['<str>', '<str>', ...]"
PANTS_SCALAPB_JVM_PLUGINS
pants.toml
[scalapb]
jvm_plugins = [
    '<str>',
    '<str>',
    ...,
]
default: []

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.)

Advanced options​

artifacts​

--scalapb-artifacts="['<str>', '<str>', ...]"
PANTS_SCALAPB_ARTIFACTS
pants.toml
[scalapb]
artifacts = [
    '<str>',
    '<str>',
    ...,
]
default: 
[
  "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.

jvm_options​

--scalapb-jvm-options="['<str>', '<str>', ...]"
PANTS_SCALAPB_JVM_OPTIONS
pants.toml
[scalapb]
jvm_options = [
    '<str>',
    '<str>',
    ...,
]
default: []

List of JVM options to pass to scalapb JVM processes.

Options set here will be added to those set in [jvm].global_options. Please check the documentation for the jvm subsystem to see what values are accepted here.

lockfile​

--scalapb-lockfile=<str>
PANTS_SCALAPB_LOCKFILE
pants.toml
[scalapb]
lockfile = <str>
default: <default>

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_2.18.3/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.

version​

--scalapb-version=<str>
PANTS_SCALAPB_VERSION
pants.toml
[scalapb]
version = <str>
default: 0.11.6

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