FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
Compilation failed; see the compiler error output for details.
This is from the build.gradle
buildscript {
ext {
buildToolsVersion = "28.0.3"
minSdkVersion = 19
compileSdkVersion = 28
targetSdkVersion = 27
supportLibVersion = "28.0.0"
RNNKotlinVersion = "1.3.61" // Or any version above 1.3.x
RNNKotlinStdlib = "kotlin-stdlib-jdk8"
}
repositories {
google()
mavenLocal()
mavenCentral()
jcenter()
maven { url "$rootDir/../node_modules/react-native/android" }
maven { url 'https://maven.google.com' }
// ADD THIS
maven { url "https://www.jitpack.io" }
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.61"
classpath 'com.android.tools.build:gradle:3.6.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
this if from the app build.gradle
dependencies {
implementation project(':#react-native-community_async-storage')
implementation project(':react-native-linear-gradient')
implementation project(':react-native-image-crop-picker')
implementation project(':react-native-vector-icons')
implementation "androidx.appcompat:appcompat:1.0.0"
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
implementation "com.facebook.react:react-native:+" // From node_modules
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:design:27.1.0'
}
This is the mainapp
public class MainApplication extends NavigationApplication {
private final ReactNativeHost mReactNativeHost =
new NavigationReactNativeHost(this) {
#Override
public boolean isDebug() {
return BuildConfig.DEBUG;
}
#Override
protected List<ReactPackage> getPackages() {
#SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
// Packages that cannot be autolinked yet can be added manually here, for example:
// packages.add(new MyReactNativePackage());
return packages;
}
#Override
protected String getJSMainModuleName() {
return "index";
}
};
#Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
#Override
public void onCreate() {
super.onCreate();
initializeFlipper(this, getReactNativeHost().getReactInstanceManager());
}
main activigty just looks like this
package com.battlebuddy;
import com.reactnativenavigation.NavigationActivity;
public class MainActivity extends NavigationActivity {
}
If there is anything you can think of that would help a lot
