响应本机任务：“compileJava”任务(当前目标为1.8)和“compileKotlin”任务(当前目标为11)

Question

大家好，我试图创建和运行一个反应本地应用程序。我运行npx react-native init rn4，但当我运行npm run android时，出现了以下错误：

> Task :react-native-gradle-plugin:compileKotlin
'compileJava' task (current target is 1.8) and 'compileKotlin' task (current target is 11) jvm target compatibility should be set to the same Java version.

我还运行了cd android && ./gradlew clean，输出是：

这是android/gradle/wrapper/gradle-wrapper.properties中的文件

distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip
zipStoreBase=GRADLE_USER_HOME

这是我运行./gradlew --version时的输出

我读过类似的文章，但一直没能解决。有了几天前我创建的文件夹，我在运行这个应用程序时没有问题。

有人能帮我吗？非常感谢！

Answer 1

如果您使用的是Reactinative女巫巧克力，则必须将JDK版本更新为11。

为了执行更新，在PowerShell中执行此操作(具有管理权限)：

choco install -y openjdk11

在此之后，第一次(仅仅是第一次)运行npm android时，您会收到很多警告，但是项目的构建将正常工作。

如果继续收到错误，可能需要调整项目的gradle版本，使其与新的JDK版本兼容。

您可以通过编辑文件YOUR_PROJECT\android\gradle\wrapper\gradle-wrapper.properties来实现这一点。

将distributionUrl版本更新为7.4.2

我希望我能帮上忙

Answer 2

信息终于消失了。

在此之前，使用Mac执行以下iam操作

1. 安装了JDK11并安装了家庭设备
2. 如果您有任何旧版本或安装了最新的18，而不像错误中提到的那样。然后按照这个URL删除安装，并通过以下操作确保正确设置路径--引用得分最高的路径
3. 现在，要设置路径，请遵循这个URL。由Arv编写
4. 现在在android文件夹android/.idea/compiler.xml中查找这个文件，并将目标设置为"1.8“，改为"11”。

​

1. 运行./gradlew干净运行它twice..else相同的消息将是可见的

Answer 3

我刚刚安装了jdk11，然后运行对我有用的cd ./android/ && ./gradlew clean
