hey, anyone been porting gradle to use kotlin dsl? I'm trying to but no matter what, I get > The 'java' plugin has been applied, but it is not compatible with the Android plugins.
My guess is that kotlin-dsl plugin includes java plugin which interferes with android plugin. Anyway, I have literally no idea how to repair it

[Bruno_]

Normally I could just delete this plugin but I can't since I'm using .kt file with dependencies

[Bruno_]

in module which causes the problem I only have kotlin-android-extensions and com.android.application plugins, in addition I import dependencies from buildSrc module with kotlin-dsl plugin

My guess is that kotlin-dsl plugin includes java plugin which interferes with android plugin

Why do you apply kotlin-dsl plugin? this is need only if you want to develop own Gradle plugin and use Kotlin-DSL extensions

[gildor]

you shouldn’t use it for Android library/application module

[gildor]

You shouldn’t have such problem and kotlin-dsl shouldn’t cause any problems, maybe you could show some example

@gildor yeah sure will send these in a second, but one more thing: one of the dependencies needs kotlin-android plugin, which seems that it doesn't exist, right?
http://central.maven.org/maven2/org/jetbrains/kotlin/
or at least I can't find one

[Bruno_]

if I do include it (apply plugin: 'kotlin-android'), gradle tells me that it can't find it

Extension with name 'android' does not exist. Currently registered extension names: [ext, sonarqube, defaultArtifacts, reporting, sourceSets, java, kotlin]

[Bruno_]

it looks somewhat like this

it's a work in progress so it may not be the preetiest code you see

[gildor]

You should use plugins DSL to use static accessors

[gildor]

See this example
https://github.com/gradle/kotlin-dsl/tree/master/samples/hello-android

[gildor]

Also official migration guide is very helpful and explains how to apply plugins to use static accessors

@gildor sorry to bother you again, but there's one thing that's confusing to me
when exactly should I use kotlin-dsl plugin?

[gildor]

When: if you need some Kotlin DSL helpers for you custom Gradle plugin
Where: in buildSrc if you have custom plugin there or in standalone plugin's build.gradle
