I have a live react native app, which was working fine. But now I need to made some changes to it but I am unable to do so after new updates and new gradle version. I have tried on multiple PCs and workspaces but all are of no use same error on every system pops up. giving some errors which are as under and attached screenshot.
FAILURE: Build failed with an exception.
The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build.
This might happen in subprojects that apply the Kotlin plugins with the Gradle 'plugins { ... }' DSL if they specify explicit versions, even if the versions are equal.
Please add the Kotlin plugin to the common parent project or the root project, then remove the versions in the subprojects.
If the parent project does not need the plugin, add 'apply false' to the plugin line.
See: https://docs.gradle.org/current/userguide/plugins.html#sec:subprojects_plugins_dsl
The Kotlin plugin was loaded in the following projects: ':react-native-alarm-clock', ':react-native-webview'
What went wrong:
Execution failed for task ':invertase_react-native-apple-authentication:compileDebugKotlin'.

add kotlin version in you android/build.gradle
buildscript {
ext {
...
kotlin_version='1.6.0' //add This change version with your installed kotlin version
...
}
repositories {
google()
mavenCentral()
}
dependencies {
...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" //add This
...
}
}
Just go to build.gradle(Project:yourProjectName)
change
Plugin {
...
id 'org.jetbrains.kotlin.android' version '1.4.x' apply false
...
}
To
Plugin {
...
id 'org.jetbrains.kotlin.android' version '1.6.0' apply false
...
}
I'm a beginner with gradle and would like to use koin in my Kotlin project.
However, I get the following error
Execution failed for task ':compileTestKotlin'.

This is my gradle.build.kts file
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
val koinVersion = "3.2.0-beta-1"
plugins {
kotlin("jvm") version "1.6.20"
kotlin("plugin.serialization") version "1.6.10"
application
}
group = "org.example"
version = "1.0-SNAPSHOT"
repositories {
mavenCentral()
}
dependencies {
implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.3.2")
implementation("io.insert-koin:koin-core:$koinVersion")
testImplementation("io.insert-koin:koin-test:$koinVersion")
testImplementation("io.insert-koin:koin-test-junit5:$koinVersion")
testImplementation("com.willowtreeapps.assertk:assertk-jvm:0.25")
testImplementation(kotlin("test"))
}
tasks.test {
useJUnitPlatform()
}
tasks.withType<KotlinCompile> {
kotlinOptions.jvmTarget = "1.8"
}
application {
mainClass.set("MainKt")
}
It looks like there are 3 problems
As I mentioned in the comment, the Kotlin JVM and Serialization plugins have mismatched versions. These should always be the same!
plugins {
kotlin("jvm") version "1.6.21"
kotlin("plugin.serialization") version "1.6.21"
application
}
However, as you discovered, it still doesn't work. There's a larger error message, with three errors.
Could not resolve io.insert-koin:koin-test-junit5:3.2.0-beta-1
Could not resolve org.jetbrains.kotlin:kotlin-test-junit5:1.6.21
Could not resolve org.jetbrains.kotlin:kotlin-test-junit:1.6.10
Let's go through them one-by-one
Java 11 library, Java 8 project
Here's the reason that Gradle gives for the first failure:
Could not resolve io.insert-koin:koin-test-junit5:3.2.0-beta-1.
No matching variant of io.insert-koin:koin-test-junit5:3.2.0-beta-1 was found. The consumer was configured to find an API of a library compatible with Java 8, preferably in the form of class files, preferably optimized for standard JVMs, and its dependencies declared externally, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm' but
Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8
The component, koin-test-junit5, is only compatible with Java 11, but your project needs Java 8 (kotlinOptions.jvmTarget = "1.8").
Let's fix this first, using Gradle Toolchain
tasks.withType<KotlinCompile>().configureEach {
kotlinOptions.jvmTarget = "11"
}
kotlin {
jvmToolchain {
(this as JavaToolchainSpec).languageVersion.set(JavaLanguageVersion.of(11))
}
}
That resolves the Java version mis-match, and leaves two more errors.
conflict on capability - incompatible libraries
Cannot select module with conflict on capability
Cannot select module with conflict on capability 'org.jetbrains.kotlin:kotlin-test-framework-impl:1.6.10' also provided by [org.jetbrains.kotlin:kotlin-test-junit:1.6.10(junitApi)]
Cannot select module with conflict on capability 'org.jetbrains.kotlin:kotlin-test-framework-impl:1.6.10' also provided by [org.jetbrains.kotlin:kotlin-test-junit5:1.6.10(junit5Api)]
Understanding this one requires quite a bit of knowledge of how Gradle selects versions.
tl;dr: org.jetbrains.kotlin:kotlin-test-junit and org.jetbrains.kotlin:kotlin-test-junit5 are incompatible. You can only use one or the other - not both
I don't really understand what Koin needs to work best. It looks like it has a hard dependency on JUnit5, so you'd have to use these dependencies, and wouldn't be able to use kotlin("test")
dependencies {
implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.3.2")
implementation("io.insert-koin:koin-core:$koinVersion")
testImplementation("io.insert-koin:koin-test:$koinVersion")
testImplementation("io.insert-koin:koin-test-junit5:$koinVersion")
testImplementation("com.willowtreeapps.assertk:assertk:0.25")
testImplementation("org.junit.jupiter:junit-jupiter:5.8.2")
// incompatible with JUnit 5, which I think is required by Koin?
// testImplementation(kotlin("test"))
}
Explanation
In short, when you use Gradle to build a library, you can declare 'attributes'. They're free-form strings, so they can really be anything. They describe things like "this library needs Java 11" or "this is test coverage data".
Some attributes are important to Gradle resolving a project's dependencies. The error you originally got was caused by one such attribute: 'capability'. It describes the Maven coordinates that the library produces.
In the case of the Maven coordinates, if they clash, then Gradle doesn't know what to do, and throws an error. It's up to the user to fix it. There's a lot of Gradle docs about conflict resolution, but usually the simplest answer is to is remove any conflicting dependencies.
What's interesting about capabilities is that because it's just a string, you can add anything to it. And what the authors of org.jetbrains.kotlin:kotlin-test-junit5 and org.jetbrains.kotlin:kotlin-test-junit have done is given them both the same capability.
org.jetbrains.kotlin:kotlin-test-framework-impl:1.6.10
If you search for this library you'll find it doesn't exist. That's because the capability is completely artificial! The authors have made it up, specifically so Gradle will throw an error, and it's up to the user to fix it.
So that's the fix: choose either kotlin-test-junit or kotlin-test-junit5, because you can't have both.
I think org.jetbrains.kotlin:kotlin-test-junit5 has problem with dependencies.
I also struggled with the same issue, so I tried multiple solutions but it all fails.
And I realized that, when just add dependency for kotlin-test-junit5, the kotlin-test-junit is also added to the external libraries.
So here's the working solution for me.
I added this line to gradle first to enable useJunitPlatform()
tasks.withType<Test> {
useJUnitPlatform()
}
after that, i exclude kotlin-test-junit from every references like this,
testImplementation("io.ktor:ktor-server-tests-jvm:$ktorVersion")
testImplementation("org.jetbrains.kotlin:kotlin-test-junit5:$kotlinVersion") {
exclude(group = "org.jetbrains.kotlin", module = "kotlin-test-junit")
}
// Dependency Injection
val koinVersion: String by project
implementation("io.insert-koin", "koin-ktor", koinVersion)
implementation("io.insert-koin", "koin-logger-slf4j", koinVersion)
testImplementation("io.insert-koin", "koin-test-junit5", koinVersion) {
exclude(group = "org.jetbrains.kotlin", module = "kotlin-test-junit")
}
After that, junit5 test was working perfectly.
I have tried migrating to a new Gradle Plugin, but since we have some custom layouts for AndroidTests, it fails with an error saying "R class was not found" for the android tests.
I could not find any source saying about any behaviour changes in this area.
The error looks like this and seems to be related to view inding or simply to the fact the R class is not generated.
/pathToTheApp/build/generated/data_binding_base_class_source_out/debugAndroidTest/out/com/package1/test/databinding/CustomViewActivityBinding.java:12: error: cannot find symbol
import package.name.test.R;
^
symbol: class R
location: package package.name.test
I had this problem in our Android tests after upgrading to AGP 7.0. Our test R class could not be found. I managed to fix it by duplicating the testApplicationId into the seemingly new testNamespace field.
android {
testNamespace = "com.example.tests"
defaultConfig {
testApplicationId "com.example.tests"
}
}
I think it should work without it, so maybe this is a plugin bug, but the docs say:
The namespace used by the android test and unit test components for the generated R and BuildConfig classes
I have a flutter web project and I was trying to implement a payment solution. I found out that paytabs is a good choice for my situation. I wanted to add their api but I kept getting the CORS erorr over my flutter website. So I tried their ready payment page but I am also unable to implement since I have no previous knowledge about web development. I only use dart and flutter. But I would like to implement the api since it gives higher control. This is the url used for post requests https://www.paytabs.com/apiv2/create_pay_page Using the http package I always have the CORS appearing as an error. Documentation for the paytab service: https://dev.paytabs.com/docs/paypage/ Hope you can help
There are not payment plugins available for flutter.
but we can integrate PayTabs by using flutter platform channel.
step 1-> Create the Flutter platform client final Map result = await methodChannel.invokeMethod('getPayTabs');
Exemple :`
Future<void> _getPayTabs() async {
String batteryLevel;
try {
debugPrint("this is dart getPayTabs");
final Map result = await methodChannel.invokeMethod('getPayTabs');
debugPrint("trasiction data $result");
} on PlatformException {
debugPrint("trasiction data Failed");
}
step 2-> Importing the SDK android project
In Android Studio, Right click on the app choose New > Module
Choose the Downloaded paytabs_sdk-v4.0.1.aar. If not, download here
Right click on your App and choose Open Module Settings
Add the Module dependency
Choose the: paytabs_sdk-v4.0.1 module to be included
Confirm the Module import by changing the Android view to Project view in the sidebar
Add below dependencies.
You can start with code changes.
You have to include the following dependencies:
allprojects {
repositories {
...
maven {
url 'https://jitpack.io'
}
}
}
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
implementation 'com.github.dbachelder:CreditCardEntry:1.4.9'
step 3-> Add an Android platform-specific implementation
Start by opening the Android host portion of your Flutter app in Android Studio:
Open the file MainActivity.kt located in the kotlin folder in the Project view. (Note: If editing with Android Studio 2.3, note that the kotlin folder is shown as if named java.)
Inside the configureFlutterEngine() method, create a MethodChannel and call setMethodCallHandler(). Make sure to use the same channel name as was used on the Flutter client side.
You need to override your Activity’s onActivityResult
I try to build an application in my MacBook and it doesn't build with realm. Two errors occur when I wanna build on android:
1) A problem occurred configuring project ':realm'.
2) A problem occurred evaluating project ':realm'. Extension not initialized yet, couldn't access compileSdkVersion. and in iOS, it says it couldn't find the realm constructor.
I've already checked the compilesdk versions on the main gradle file and in the realm module's gradle file. they look fine.
