Hello, even I use

kapt{ annotationProcessor("foo.bar.Aprocessor") }

. The gradle show me that Can't find annotation processor. Before that, I use

kapt/compileOnly("com.google.auto.service:auto-service:1.0-rc7")

in the processor build file. And use

kapt/compileOnly(project("codegen", "default"))

in the parent project (which use the annotation in fact.) Thank you for your help.

Just use kapt("foo.bar.Aprocessor") and you need to apply the plugin https://kotlinlang.org/docs/reference/kapt.html

I applied this plugin And:

Supplied String module notation 'space.iseki.codegen4vertx.Codegen' is invalid. Example notations: 'org.gradle:gradle-core:2.2', 'org.mockito:mockito-core:1.9.5:ja
vadoc'.

When I use

kapt("space.iseki.codegen4vertx.Codegen")

Where are you getting the dependency from? MavenCentral, JCenter, is it local on your computer?

It's child module.

include("codegen")

try kapt project(":codegen")

Yeah. I have tried.

Don't know if this helps, but in this project, i used an annotation processor from an module https://github.com/Foso/ExtensionGenerator

I use it like you exactly.😥 Only difference is I put the

app

as the parent module
