After upgrade AS to next canary version receive error during gradle sync

Please initialize at least one Kotlin target in

despite the fact all was good on previous version

Now i’ve updated canary 14 to canary 15 (updated AGP plugin as well)

Early i got this error when updated from 13 to 14 (that time it was resolved after reinstalling AS: downgrading to 13 and updating to 14 again). I can try to repeat this way, but it is strange ) Have anyone stucks with that error? Is it happens after each upgrade? How can i fix it?

if you run gradlew build, you get the same error?

[iamthevoid]

Hm. There was message about upgrade gradle wrapper from 7.0-rc-1 to 7.0. After upgrade my functions from bulildSrc became unresolved(

Strange thing is no errors in editor, only during build time

[Javier]

copy the error when you run gradlew build

[Javier]

in terminal

[Javier]

have you using version catalogs?

have you using version catalogs?

What do you mean?

[iamthevoid]

Hmm, maybe my buildSrc code broken becuse of gradle update?

[tapchicoma]

remove buildSrc/build and try to re-run

[iamthevoid]

I’m getting the same error after buildSrc rebuilded

[Javier]

if you open those files, they are correct?

[iamthevoid]

All seems ok. Let me to introduce. I take type from android fun receiver and use it in my own extension

[iamthevoid]

But i’ve found funny thing. If i change signature from extension to usual (implicit receiver) i got type mismatch

[iamthevoid]

Actual type from android lambda is not the same as expected

[iamthevoid]

Looks like bug?

[iamthevoid]

And if i try to extend inferred type com.android.build.api.dsl.LibraryExtension i get fail. Because it hardly parametrisd with 5 generic types

package com.android.build.api.dsl

import com.android.build.api.variant.LibraryVariantBuilder
import com.android.build.api.variant.LibraryVariant
import org.gradle.api.Incubating
import org.gradle.api.NamedDomainObjectContainer

/**
 * Extension for the Android Library Gradle Plugin.
 *
 *
 * Only the Android Gradle Plugin should create instances of this interface.
 */
@Incubating
interface LibraryExtension<
        AndroidSourceSetT : AndroidSourceSet,
        BuildTypeT : LibraryBuildType<SigningConfigT>,
        DefaultConfigT : LibraryDefaultConfig<SigningConfigT>,
        ProductFlavorT : LibraryProductFlavor<SigningConfigT>,
        SigningConfigT : ApkSigningConfig> :
    CommonExtension<
        AndroidSourceSetT,
        LibraryBuildFeatures,
        BuildTypeT,
        DefaultConfigT,
        ProductFlavorT,
        SigningConfigT,
        LibraryVariantBuilder,
        LibraryVariant>,
    TestedExtension {
    // TODO(b/140406102)

    /** Aidl files to package in the aar. */
    val aidlPackagedList: MutableCollection<String>?

    /**
     * container of Prefab options
     */
    val prefab: NamedDomainObjectContainer<PrefabPackagingOptions>
}

[iamthevoid]

Looks like this type should not be returned from lamda in Project.'android' fun

[iamthevoid]

Fixed this way ¯\_(ツ)_/¯

[Javier]

I remember doing that some time ago, maybe I filed an issue for a similar problem 🤔

[iamthevoid]

Now there are multiple problem in file, even after clean, relaunch etc… But project builds

[iamthevoid]

All types from popup are parents of LibraryExtensions

[Javier]

Change the JDK

[iamthevoid]

Hmmm. Cannot find this option in project settings, where it was before. How can i do it? And which version shouls i use?

[iamthevoid]

message has been deleted

[iamthevoid]

tried set JAVA_HOME to jdk 11 and 16 location, but have no positive result

[Javier]

It should be in project but maybe they moved to Gradle settings

[iamthevoid]

You’re correct. But it doesn’t help

[iamthevoid]

Looks like LibraryExtensions receiver type in lambda changed in AGP alpha15 (checked that with different AGP versions). And new com.android.build.api.dsl version of LibraryExtensions is burried somewhere in AGP-alpha15 dependencies (not transitive). Downgraded to alpha14 for the present. Want to check this in next version of AGP

[Javier]

There are a lot of problems with this AGP version, I think yesterday I saw a thread similar to this which points to an issue in google issue tracker
