Change output directory of generated code in gradle

Question

Project contains annotation processor which generates java code during compilation. By default, gradle outputs generated source files into build/classes directory.

Answer 1

By default generated Java files are under $generatedFilesBaseDir/$sourceSet/$builtinPluginName, where $generatedFilesBaseDir is $buildDir/generated/source/proto by default, and is configurable. E.g.,

protobuf {
 ...
  generatedFilesBaseDir = "$projectDir/src/generated"
}

The subdirectory name, which is by default $builtinPluginName, can also be changed by setting the outputSubDir property in the builtins or plugins block of a task configuration within generateProtoTasks block (see previous section). E.g.,

{
  task ->
  task.plugins {
    grpc {
    // Write the generated files under
    // "$generatedFilesBaseDir/$sourceSet/grpcjava"
    outputSubDir = 'grpcjava'
    }
  }
}
