Is there a way to suppress

Kotlin plugin should be enabled before 'kotlin-kapt'

error message? I have gradle script like this:

plugins {
    kotlin("kapt") version Versions.kotlin
}

subprojects {
    kapt {
        useBuildCache = true
    }
}

Basically, I want to automatically enable build cache on all projects. But since some projects are android and some are regular kotlin, I cannot apply any plugin in this root gradle script, I only need the kapt.

I would apply kapt plugin explicitly on every module where you need it

I do that already

but then I would have to copy paste this useBuildCache block to every submodule gradle file

Ah, I got what you want

which would clutter the scripts

you need another approach

project.plugins.withId(“kotlin-kapt”) { kapt { useBuildCache = true } }

but script still wouldn't compile, right?

gildor

or even better use it by type

Matej Drobnič

10/15/2019, 7:47 AM

since plugin would not be declared

gildor

You have to specify type

project.plugins.withType<KaptPlugin>

(not sure about class of KaptPlugin tho

But in general, you don’t need all this stuff

just set

kapt.useBuildCache=true

to your gradle.properties

It's

Kapt3GradleSubplugin

thanks for both workarounds

another good way to do it that is more general is with

project.pluginManager.withPlugin("com.android.application") {
      apply from: "${rootProject.projectDir}/gradle/defaultConfig.androidApp.gradle"
    }

that will detect the plugin having been applied and once the plugin.apply returns it will run your config block

I do this is our project so that all the library build files end up as just:

plugins {
  `android-library`
}
dependencies {
  ...
}

same for

kotlin("jvm")

etc…

plugins {
    kotlin("kapt") version Versions.kotlin apply false
}

apply false would disable Kotlin DSL type safe accessors and snippet above will be broken

Yeah... I got your point.
