In the new version (7.2) of Gradle some parts is changed, so you need to do like this:
1-Check your gradle version
2- Open the build.gradle(project:---)
3- If like the below code, go to next
plugins {
id 'com.android.application' version '7.1.2' apply false
id 'com.android.library' version '7.1.2' apply false
}
task clean(type: Delete) {
delete rootProject.buildDir
}
4- Open stting.gradle(---)
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' }
}
5- Sync Now and finish

please help i cant even upload my library to my server, and it works fine in previous android studio
are you sure it doesn't exists in directory {apps dir}/outputs/aar/${artifactId}-erelease.aar . The file name should <your_artifact_id>-erelease.aar inside /aar directory.
can you show me the changes code on build.gradle, specially on Publishing.publication part?

The build.gradle snippet you posted looks like the config inside your app module. What does the build.gradle in your project's root directory look like? To add the kotlin plugin dependencies it should look something like this:
buildscript {
ext.kotlin_version = '1.6.10'
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-beta6'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
The important part being the line classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"which adds the kotlin plugins.
To use the plugin, you have to add it in your root build.gradle file
buildscript {
ext.kotlin_version = '1.1.60'
repositories {
jcenter()
maven {
url 'https://maven.google.com'
}
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
In Android Studio we can fix it in following ways:_
Using the plugins Domain Specific Language (DSL) in App Level Graddle:
plugins {
id "org.jetbrains.kotlin.android.extensions" version "1.4.21"
}
That's all to fix it.
But if you're using legacy plugin application, then add the following in App Level Gradle:
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.21"
}
}
apply plugin: "org.jetbrains.kotlin.android.extensions"
Hopefully, it'll be helpful!
put the below lines in build.gradle app
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
and also do changes in build gradle by adding kotlin extension and path
//put the ext above the dependency line//
ext.kotlin_version = '1.4.31'
dependencies {
classpath "com.android.tools.build:gradle:4.2.1"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
Im trying to integrate a "module"-project generated by swagger-codegen, into my Android project.
Haven't worked that much with gradle before and the swagger-codegen creates a quite messy build.gradle from my point of view.
I have a hard time finding documentation on how to do this. And I feel a bit lost.
I used this method described in the FAQ
mvn clean package
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
-i http://petstore.swagger.io/v2/swagger.json \
-l java --library=okhttp-gson \
-o /var/tmp/java/okhttp-gson/
So fare I tried to copy the source from the project that was generated by swagger-codegen and merge the two gradle build files. I removed the Junit tests because I couldn't get the Junit dependency working (Implementing Swagger-codegen project - Error:(23, 17) Failed to resolve: junit:junit:4.12). But then I got stuck with some conflict between the plugins?
The 'java' plugin has been applied, but it is not compatible with the Android plugins.
Here's the build.gradle:
import static jdk.nashorn.internal.runtime.regexp.joni.ApplyCaseFold.apply
apply plugin: 'idea'
apply plugin: 'eclipse'
group = 'io.swagger'
version = '1.0.0'

Am I doing something complete wrong here? What is the correct way to implement swagger-codegen code into my project?
The swift way to import it was to compile the swagger generated project then copy the .jar file to my android project and add its as a library.
I have a hard time finding documentation on how to do this. And I feel a bit lost.
You could clone the Android swagger-codegen example.
(which does use Junit, so I'm not sure what error you got)
Unless that's what you mean by
So far I tried to copy the source and merge the two gradle build files
To which, I ask, what two Gradle files? It looks like you merged an Android Gradle file with a Java Gradle file, which seems to causing more issues because you are getting...
The 'java' plugin has been applied, but it is not compatible with the Android plugins.
Which seems pretty self explanatory when you have this line
apply plugin: 'java'
It's not too clear what you are trying to do here other than check the build target
if(hasProperty('target') && target == 'android')
I am trying to try out Kotlin and the Kotlin Android extensions in Android Studio. I have tried this both in Android Studio v 1.5.1 on Ubuntu 14.04, and in Android Studio v 1.5.1 on OS X El Capitan with the same result.
Here is what I am doing:
I install the Kotlin plugin 1.0.0-beta-35950-IJ141-11
Create a new blank Android project
Convert the MainActivity file to Kotlin (via help->findaction->convert file to kotlin)
Configure the project for Kotlin
I then go into the generated content_main.xml file and add an id (hello) for the "Hello World!" TextView.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.gmail.npnster.mykotlinfirstproject.MainActivity"
tools:showIn="#layout/activity_main">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:id="#+id/hello"
/>
</RelativeLayout>
Then in the converted MainActivity I add a line to set the TextView. (shown below).
Android Studio then prompts me (via alt-enter) to insert this line (also shown below)
import kotlinx.android.synthetic.main.content_main.*
So at this point everything seems fine
but then when I try to compile this I get
Unresolved reference: kotlinx
Unresolved reference: kotlinx
Unresolved reference: hello
Notice that I did not install the Kotlin Android extensions plugin. As of a couple of days ago this is now supposed to be included in the main plug in and is marked as obsolete. (In fact if you try to install it when you have the latest plugin, nothing new is installed)
Anyone see what I am doing wrong?

import android.os.Bundle
import android.support.design.widget.FloatingActionButton
import android.support.design.widget.Snackbar
import android.support.v7.app.AppCompatActivity
import android.support.v7.widget.Toolbar

setContentView(R.layout.activity_main)
val toolbar = findViewById(R.id.toolbar) as Toolbar
setSupportActionBar(toolbar)
print("setting text view value to hey")
hello.text = "hey"
val fab = findViewById(R.id.fab) as FloatingActionButton
fab.setOnClickListener { view -> Snackbar.make(view, "Replace this with your own action", Snackbar.LENGTH_LONG).setAction("Action", null).show() }
}
override fun onCreateOptionsMenu(menu: Menu): Boolean {
// Inflate the menu; this adds items to the action bar if it is present.
menuInflater.inflate(R.menu.menu_main, menu)
return true
}
override fun onOptionsItemSelected(item: MenuItem): Boolean {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
val id = item.itemId
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true
}
return super.onOptionsItemSelected(item)
}
}
Add kotlin-android-extensions in our buildscript's dependencies:
1. In your project-level build.gradle
buildscript {
dependencies {
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
}
}
and apply the kotlin-android-extensions plugin:
2. In your module-level build.gradle
apply plugin: 'kotlin-android-extensions'
When you use Android Studio 2.0 and kotlin 1.0.1-2, you will come up with the same wrong. You cann't configure kotlin android extensions in your project's build.gradle, you need to configure and kotlin android extensions in every Module's build.gradle like this:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
buildscript {
ext.kotlin_version = '1.0.1-2'
repositories {
jcenter()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
}
}
android {
compileSdkVersion 23
buildToolsVersion "24.0.0 rc2"
defaultConfig {
applicationId "com.dazd.kotlindemo"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}
Most importantly, even through the kotlin plugin included the kotlin android extension, you also need to configure the kotlin-android-extensions in your Module's bulid.gradle like this:
...
apply plugin: 'kotlin-android-extensions'
...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
Of course, you could configure the kotlin plugin's classpath in your project's build.gradle.
I can't find it in the official documentation, but you must apply the plugin by adding the following to your build.gradle file:
apply plugin: 'kotlin-android-extensions'
The buildscript block containing the kotlin-android-extensions dependency apparently needs to be in the app-module build.gradle, not in the top-level one.
I found why mine didn't work. My blocks were misplaced and by moving the buildscript{} block before the plugins as follow I got it working:
buildscript {
ext.kotlin_version = '1.0.0-beta-3595'
ext.anko_version = '0.8.1'
repositories {
jcenter()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
}
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.kotlin"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
compile "org.jetbrains.anko:anko-sdk15:$anko_version"
compile "org.jetbrains.anko:anko-support-v4:$anko_version"
}
Removing the following import fixed the issue for me.
import android.R
add apply plugin: 'kotlin-android-extensions' in app/buildgradle.
if you have already added it, try to remove it and sync gradle, when sync is complete, then add it back and Sync Gradle again. This work for me.
The problem for me was the order in which I applied the plugins.
You must apply the kotlin-android plugin before the kotlin-android-extensions plugin
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
What worked for me in Android Studio 4.2 Beta 1 in macOS big sur to add id 'kotlin-android-extensions' to plugin section in app-level build.gradle file. So that it should look as follows.
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
}
Then sync the project and it should work
With jetpack you have to use:
in the build.gradle (app)
buildFeatures {
dataBinding true
viewBinding true
}
plugins {
id 'kotlin-parcelize'
}
In activity_main.xml
<androidx.constraintlayout.widget.ConstraintLayout
tools:viewBindingIgnore="false">
In MainActivity.kt
import com.example.appname.databinding.ActivityMainBinding // ActivityMain is for main_activity.xml, and so on for any other activity
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
val view = binding.root
setContentView(view)
binding.button.setOnClickListener {} // use binding.elementName
}
}
After applying the fixes mentioned above, I had to restart Android Studio to make it work.
If you are in the year 2021 then i guess most of the solutions you see here wont be of any help to you so try this instead
Go to your Module build.gradle file
add id 'kotlin-android-extensions' to the plugins object {}
Go to file the click on sync project with gradle files
Then go back and try to import kotlinx and that should work
In my case, adding:
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
at the end of the module-level build.grade fixed the issue.
Had same issue
plugins {
id 'com.android.application'
id 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: "kotlin-kapt"
}
removed apply plugin: to idand restarted
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
id "kotlin-kapt"
}
This is how it worked for me.
When I first configured Kotlin in Project, I selected the 1.1.2-3 version instead of 1.1.2-4 and added the following line in the build.gradle app file
apply plugin: 'kotlin-android-extensions'
after that I synced the build and it worked as expected.
I found out that I had support for C++ and Kotlin at the same time which was causing build problems.
When starting a new project, ensure C++ support is unchecked, and Kotlin support is checked. That fixed the problem for me.
In my case, I had put the code referring the view in a companion object. How silly..
For me the only thing that helped was to click "File" -> "Invalidate caches / Restart..."
in my case android studio line separator changed to CRLF( I am using macbook) windows settings.
when switch to CR fix my error
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
}
For me I just had to add id 'kotlin-android-extensions' to plugins in build.gradle(Module:AppName.app)
And Sync it after that.
use this plug-in in your app project "Gradle script" folder in file "build.Gradle (Modules : progect_name)" :
"Kotlin-android-extensions"
then sync the projects.
