在 React Native Expo 中使用 Bare Workflow 启用 Kotlin 存在困难

Jos*_*e A 5 android gradle kotlin react-native expo

说我花了大约 32 个小时还算轻描淡写。我一直在尝试在由 Expo SDK 44 提供支持的 React Native 项目中启用 Kotlin。

\n

我一直在尝试在互联网上找到的所有方法，但总是在 EAS 的 Gradle 阶段出现错误（使用运行它eas build --profile development --platform android）。

\n

这是我的配置：

为了简洁起见，我省略了代码。如果您需要更多背景信息，请告诉我

应用程序\\android\\build.gradle：

\n

buildscript {\n    ext {\n        buildToolsVersion = "30.0.2"\n        minSdkVersion = 21\n        compileSdkVersion = 31\n        targetSdkVersion = 31\n        kotlinVersion = "1.4.11"\n    }\n    repositories {\n        google()\n        mavenCentral()\n        jcenter()\n    }\n    dependencies {\n        classpath("com.android.tools.build:gradle:4.1.0")\n        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")\n       \n        // NOTE: Do not place your application dependencies here; they belong\n        // in the individual module build.gradle files\n    }\n}\n

以下是我尝试过的一些错误和修复：

\n

1 - 将项目最小化到准系统 Kotlin

\n

我已经尝试最小化地增加我当前的项目（请注意，我必须将Intercom 包的compileSdkVersion和设置targetSdkVersion为 31，并且构建成功）。我已关注此视频、官方React Native 文档，以及使用 Android Studio将 Kotlin 添加到现有应用程序（手动方法）。

\n

A。（android/build.gradle）添加（在 buildscript.ext 内）kotlin_version = \'1.4.10\'\nb。（android/build.gradle）添加（内部依赖项）classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"\nc。(android/app/build.gradle) 添加（在文件顶部）apply plugin: "kotlin-android"

\n

尝试编译：

\n

2 - 将 Kotlin 推送至版本 1.6.10

\n

看到这一点，我进行了一些研究，并建议将 Kotlin 版本推送到 1.6.10：

\n

Task :expo-dev-launcher:compileDebugKotlin\n[stderr] Compilation with Kotlin compile daemon was not successful\n[stderr] java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: \n[stderr]    java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: \n[stderr]    java.io.InvalidClassException: org.jetbrains.kotlin.incremental.IncrementalModuleInfo; local class incompatible: stream classdesc serialVersionUID = 1, local class serialVersionUID = 0\n[stderr]    at java.rmi/sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:391)\n[stderr]    at java.rmi/sun.rmi.transport.Transport$1.run(Transport.java:200)\n[stderr]    at java.rmi/sun.rmi.transport.Transport$1.run(Transport.java:197)\n[stderr]    at java.base/java.security.AccessController.doPrivileged(Native Method)\n[stderr]    at java.rmi/sun.rmi.transport.Transport.serviceCall(Transport.java:196)\n[stderr]    at java.rmi/sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:562)\n[stderr]    at java.rmi/sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:796)\n[stderr]    at java.rmi/sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.lambda$run$0(TCPTransport.java:677)\n[stderr]    at java.base/java.security.AccessController.doPrivileged(Native Method)\n[stderr]    at java.rmi/sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:676)\n[stderr]    at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)\n[stderr]    at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)\n[stderr]    at java.base/java.lang.Thread.run(Thread.java:829)\n[stderr]    at java.rmi/sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:303)\n[stderr]    at java.rmi/sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:279)\n[stderr]    at java.rmi/sun.rmi.server.UnicastRef.invoke(UnicastRef.java:164)\n

这导致我更新并运行expo upgrade并expo doctor查看是否有任何更新有效。这打开了潘多拉魔盒。升级到 expo SDK 45 也有其自身的问题（显然我有一些冲突的软件包引发以下错误）：

\n

还有其他构建失败了expo-dev-client。我还知道 SDK 45 中的一个错误，即启用 Hermes 时会出现问题。我们正在使用 JSC。

\n

3 - 一堆其他的东西

\n

为了防止这个问题变得更长，我尝试过以下其他操作：

\n

A。distributionUrl将中的更改gradle-wrapper.properties为更新的 gradle 版本。

\n

b. 使用相应的 kotlin 版本更新并计算（org.jetbrains.kotlin:kotlin-gradle-plugin在 android/build.gradle 中）org.jetbrains.kotlin:kotlin-stdlib-jdk7（将其更改为 jdk8，什么都没有）。org.jetbrains.kotlinx:kotlinx-coroutines-coreorg.jetbrains.kotlinx:kotlinx-coroutines-androidandroidx.core:core-ktx

\n

C。在声明中添加了这些实现debugImplementation。

\n

d. 研究了Kotlin对应的React Native版本（不知道Expo的SDK 44 0.64版本是否支持Kotlin 1.6.10）。

\n

e. 使用 Android Studio 检查语法错误。

\n

F。跑得干净利落。

\n

G。和其他东西...

\n

有人知道吗？Expo GitHub 上似乎没有任何报道。

\n

以下打包选项似乎有助于缓解一些问题

// android/app/build.gradle
android {
    // This fixes a bug when 
    // https://github.com/facebook/react-native/issues/33120
    packagingOptions {
        jniLibs.useLegacyPackaging = true
    }
