Good morning from Germany, I have a complex multi-module project that I want to convert from Gradle to Gradle Kotlin DSL. In Gradle I moved common module configuration into separate Gradle files and applied/imported them in each module. With Kotlin DSL this does not seem to work properly. Please see https://gist.github.com/svenjacobs/3643a1ba83def5edf8a07f1d209158ef. It seems that Kotlin scripts applied via apply(from = "...") do not evaluate plugins. For instance in common.gradle.kts I get an error because implementation() is not found. I know that in this case I can use "implementation"() but that doesn't solve the actual problem. In other base modules where I load the Android plugin for instance suddenly android { ... } is not found. How do I solve this with Kotlin DSL?

See previous message, it kinda related

[gildor]

tl;dr; you don’t have static accessors in script plugins, you have a few choices: use dynamic syntax (similar to what you have when write gradle plugin) or use experimental precompiled script plugins

[gildor]

In other base modules where I load the Android plugin for instance suddenly android { ... } is not found

To have static accessor you must apply plugin using plugins dsl

[gildor]

But this also work if you apply some plugin that will apply plugin for you, so it will work as transitive dependency

[svenjacobs]

I use the plugin DSL like plugins { id("com.android.application") } but in the common build script android is still not found

[gildor]

common build script also must apply it with plugins dsl

[gildor]

but problem that script plugins do not support plugins dsl yet

[gildor]

so the only similar way is to use precompiled script plugins that support type safe accessors and plugins dsl, but they are experimental and not everything work as expected

[svenjacobs]

Hmm, I try to use buildSrc instead but how do I configure the android block for instance in a fun Project.androidProject()?

[gildor]

there are other ways to do that

[gildor]

first: you don’t have static accessors in simple buildSrc/src/kotlin source code

[gildor]

but you can add Android plugin as dependency to your buildSrc project and use it using standard Gradle plugins API like project.extension<EXTENSION_TYPE>.configure

[svenjacobs]

Okay, I will try this way

[gildor]

precompiled script plugins is another way, they support static accessors and plugins dsl, but as I said not everything work for now

[svenjacobs]

FYI I migrated the whole project to Kotlin DSL, moving common configuration into buildSrc. It was quite some work and I still have a few minor issues but all in all the project compiles and it was worth it! 😄

@gildor can you point me to some docs of precompiled script plugins ?
