我见过涉及更改类路径()和分发URL的解决方案，但我已经做了。

从我的build.gradle文件：

dependencies {
        classpath("com.android.tools.build:gradle:7.2.1")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("de.undercouch:gradle-download-task:4.1.2")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

从gradle包装

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.4.2-all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

所有这些都不能修复错误，此外，我还注意到运行gradlew清除也会引发相同的错误。

我还尝试将以下代码添加到build.gradle文件中

android {
compileOptions {
sourceCompatibility = JavaVersion.VERSION_11
targetCompatibility = JavaVersion.VERSION_11
}

kotlinOptions {
jvmTarget = JavaVersion.VERSION_11.toString()
}
}

请帮我解决这个问题，我以前经常使用世博CLI，一切都很好，所有这些都是为了学习反应本机CLI。

Answer 1

找到了解决方案，但不知道为什么会起作用

我使用以下命令启动构建

npm start

现在打开另一个终端并执行以下操作

npm run android

而不是

npx react-native start

和

npx react-native run-android

如果后者是由正式文件提出的

Answer 2

我面临的同样问题是，所有Java包都安装或同步得很完美，但是kotlin软件包没有同步，这会引发kotlin编译错误。

我通过遵循这在Android上安装kotlin软件包。

Android→首选项…→插件→浏览存储库→类型“Kotlin”在搜索框中→安装

之后，您需要从

文件->无效缓存、->失效并重新启动。

在此之后，当您的项目被重新打开和同步成功，然后清理您的项目从Build -> Clean Project。

在那之后，所有的kotlin软件包都安装得很完美。
