Android-studio ERROR: Cannot add task 'copyDebugIconFonts' as a task with that name already exists

I have React Native project. When i build Android version i get an ERROR: Cannot add task 'copyDebugIconFonts' as a task with that name already exists. And in my terminal i have this error: FAILURE: Build failed with an exception.

My build.gradle:

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.4.1")

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

        google()
        jcenter()
    }
}

My fonts.gradle:

def config = project.hasProperty("vectoricons") ? project.vectoricons : [];

def iconFontsDir = config.iconFontsDir ?: "../../node_modules/react-native-vector-icons/Fonts";
def iconFontNames = config.iconFontNames ?: [ "*.ttf" ];

gradle.projectsEvaluated {
    android.applicationVariants.all { def variant ->
        def targetName = variant.name.capitalize()
        def targetPath = variant.dirName

        // Create task for copying fonts
        def currentFontTask = tasks.create(
                name: "copy${targetName}IconFonts",
                type: Copy) {
            into("${buildDir}/intermediates")

            iconFontNames.each { fontName ->

              from(iconFontsDir) {
                include(fontName)
                into("assets/${targetPath}/fonts/")
              }

              // Workaround for Android Gradle Plugin 3.2+ new asset directory
              from(iconFontsDir) {
                include(fontName)
                into("merged_assets/${variant.name}/merge${targetName}Assets/out/fonts/")
              }

              // Workaround for Android Gradle Plugin 3.4+ new asset directory
              from(iconFontsDir) {
                include(fontName)
                into("merged_assets/${variant.name}/out/fonts/")
              }
            }
        }

        currentFontTask.dependsOn("merge${targetName}Resources")
        currentFontTask.dependsOn("merge${targetName}Assets")

        [
            "processArmeabi-v7a${targetName}Resources",
            "processX86${targetName}Resources",
            "processUniversal${targetName}Resources",
            "process${targetName}Resources"
        ].each { name ->
            Task dependentTask = tasks.findByPath(name);

            if (dependentTask != null) {
                dependentTask.dependsOn(currentFontTask)
            }
        }
    }
}

Can you help me please)

Solution

  • this package "react-native-vector-icons" has been added multiple times in your build.gradle file.

    To solve this simply go to android>build.gradle and search "react-native-vector-icons". If you found this twice then remove that line. for example i just commented out this =>

    // apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"
