Error with react-native run-android after upgrade to react-native version 0.60.4

Question

I am upgrading react-native from 0.59.5 to 0.60.4 with my existing application. But facing a problem as below

* Where:
Build file '/home/bingl/Projects/blackstar/frontend/android/app/build.gradle'

* What went wrong:
Could not compile build file '/home/bingl/Projects/blackstar/frontend/android/app/build.gradle'.
> startup failed:
  General error during semantic analysis: Unsupported class file major version 57

And my build.gradle is

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        applicationId "com.frontend"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
    }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86", "arm64-v8a", "x86_64"
        }
    }
    buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
    // applicationVariants are e.g. debug, release
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:
            // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
            def versionCodes = ["armeabi-v7a":1, "x86":2, "arm64-v8a": 3, "x86_64": 4]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }
        }
    }

I have absolutely no clue what this error is about and could not find much helpful articles. Please help me out.

Answer 1

For those who are here for java.lang.IllegalArgumentException: Unsupported class file major version 60

One of the reason for the same is:

Java version 16 installed which is not yet supported by react-native.

So For MacOS,

cd /Library/Java/JavaVirtualMachines
ls

• Check the available JDKs

• Remove the jdk-16 if present using this, sudo rm -rf jdk-16.jdk/

Basically, you can remove JDKs other than adoptopenjdk-8.jdk which will be present if you followed React-Native Env Setup.

Answer 2

In this file android/gradle/wrapper/gradle-wrapper.properties change distributionUrl on this distributionUrl=https://services.gradle.org/distributions/gradle-6.0-all.zip

Answer 3

Looks like Gradle is currently erroring on builds using openJDK-13.

Here's a Github issue thread.

Check the version of Java and JDK versions on your system by running the following command on in your terminal:

file /etc/alternatives/java /etc/alternatives/javac

OR

file `which java javac`

This will list the current installations on your system. If you see openjdk-13 anywhere, you'll have to downgrade to openjdk-8.

Check this link for downgrading steps.
