java - 升级到 react-native 版本 0.60.4 后 react-native run-android 出错

Question

我正在使用现有应用程序将 react-native 从 0.59.5 升级到 0.60.4。但面临如下问题

* 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

  java.lang.IllegalArgumentException: Unsupported class file major version 57

我的 build.gradle 是

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
            }
        }
    }

我完全不知道这个错误是关于什么的，也找不到太多有用的文章。请帮帮我。

Answer 1

对于那些在这里 java.lang.IllegalArgumentException: Unsupported class file major version 60 的人
原因之一是:
已安装 Java 版本 16，但 react-native 尚不支持。
所以对于 MacOS，

cd /Library/Java/JavaVirtualMachines
ls

检查可用的 JDK

使用此删除 jdk-16(如果存在)，sudo rm -rf jdk-16.jdk/

基本上，您可以删除 adoptopenjdk-8.jdk 以外的 JDK。如果您关注 React-Native Env Setup 将会出现.
