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

[Matej Drobnič]

I do that already

[Matej Drobnič]

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

[gildor]

Ah, I got what you want

[Matej Drobnič]

which would clutter the scripts

[gildor]

you need another approach

[gildor]

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

[Matej Drobnič]

but script still wouldn't compile, right?

[gildor]

or even better use it by type

[Matej Drobnič]

since plugin would not be declared

[gildor]

You have to specify type

[gildor]

project.plugins.withType<KaptPlugin>

[gildor]

(not sure about class of KaptPlugin tho

[gildor]

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

[gildor]

just set kapt.useBuildCache=true to your gradle.properties

[Matej Drobnič]

It's Kapt3GradleSubplugin

[Matej Drobnič]

thanks for both workarounds

[trevjones]

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"
    }

[trevjones]

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

[trevjones]

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

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

[trevjones]

same for kotlin("jvm") etc…

[Thiago Nerys]

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

[gildor]

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

[Thiago Nerys]

Yeah... I got your point.
