Cannot resolve Item , ExpandableItem, ExpandableGroup, or GroupieViewHolder

[Yasmine22]

Hello there.

As illustrated in the subject, All these classes cannot be resolved. My project is in Kotlin and here's my gradle:

My project settings:
`pluginManagement {
repositories {
google {
content {
includeGroupByRegex("com\.android.")
includeGroupByRegex("com\.google.")
includeGroupByRegex("androidx.*")
}
}
mavenCentral()
gradlePluginPortal()
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url = uri("https://jitpack.io") }
}
}

rootProject.name = "Muslim"
include(":app")`

My build.gradle (project) :

// Top-level build file where you can add configuration options common to all sub-projects/modules. plugins { alias(libs.plugins.android.application) apply false alias(libs.plugins.kotlin.android) apply false alias(libs.plugins.ksp) apply false alias(libs.plugins.dagger.hilt) apply false alias(libs.plugins.safe.args) apply false alias(libs.plugins.google.services) apply false }

My build.gradle (app):

implementation (libs.groupie) implementation (libs.groupie.kotlin.android.extensions) implementation (libs.coil)

What am I missing?

groupie-kotlin-android-extensions is dead, don't use it.

Otherwise, you should be ok if you use com.github.lisawray.groupie:groupie.

[Yasmine22]

I did. But using the new android library abbreviations, it cannot be resolved.

this is how I added it:

implementation (com.github.lisawray.groupie:groupie)

what is the correct way to add it?

[Zhuinden]

Depends on how you added it to your TOML file.
