sbt scala pb "Protobufs files found, but PB.targets is empty." - scala

Question

I'm having project which converts proto files into scala case classes.
My build.sbt is -
ThisBuild / version := "0.1.0-SNAPSHOT"
lazy val root = (project in file("."))
.settings(
name := "proto-path-error"
)
val openRtbCoreVersion = "1.5.5"
val googleCommonProtosVersion = "1.12.0"
val commonSettings: Seq[Def.Setting[_]] = Seq[Def.Setting[_]](
scalaVersion := "2.12.14",
organization := "com.td",
)
def scalaGrpcSettings: Seq[Def.Setting[_]] = Seq[Def.Setting[_]](
libraryDependencies += "com.thesamet.scalapb" %% "scalapb-runtime-grpc" % scalapb.compiler.Version.scalapbVersion,
libraryDependencies += "com.thesamet.scalapb" %% "scalapb-runtime" % scalapb.compiler.Version.scalapbVersion % "protobuf",
libraryDependencies += "com.google.api.grpc" % "proto-google-common-protos" % googleCommonProtosVersion % "protobuf",
libraryDependencies += "com.google.openrtb" % "openrtb-core" % openRtbCoreVersion,
libraryDependencies += "com.google.openrtb" % "openrtb-core" % openRtbCoreVersion % "protobuf",
PB.targets in Compile := Seq(
PB.gens.java -> (sourceManaged in Compile).value,
scalapb.gen(javaConversions = true) -> (sourceManaged in Compile).value
),
PB.includePaths in Compile := Seq(
target.value / "protobuf_external",
new File("definitions/common"),
),
PB.protoSources in Compile := Seq(
PB.externalIncludePath.value / "google" / "api",
new File("definitions/common"),
target.value / "protobuf_external"
),
excludeFilter in PB.generate := new SimpleFileFilter(file => file.getCanonicalPath.contains("google/protobuf")),
PB.additionalDependencies := Nil
)
project/plugins.sbt file is -
addSbtPlugin("com.thesamet" % "sbt-protoc" % "1.0.6")
libraryDependencies += "com.thesamet.scalapb" %% "compilerplugin" % "0.10.11"
project/build.properties is -
sbt.version = 1.3.13
The src/main/protobuf/definitions/common/common.proto -
syntax = "proto2";
option java_outer_classname = "CommonUtils";
package com.td.protobuf;
message CMap {
map<int32, Assets> cs = 1;
}
message Assets {
repeated int32 assets = 1;
}
The whole project is on github here
When I compile the project it is not producting any case classes. I'm getting below output -
$ sbt clean compile

I've 2 issues
PB.protoSources in Compile := new File("definitions/common") in build.sbt is not getting recognized.so I moved from proto-path-error/definitions to proto-path-error/src/main/protobuf/definitions.
After moving the definitions it is recognized. But scala cases classes is not getting generated. I get log [info] Protobufs files found, but PB.targets is empty.
How can I fix these 2 issues?
