javascript - react-native 是否支持 jdk 17？

Question

所以我在 android 上启动初始 react-native 模板项目时遇到了一些问题。在咨询了某人后，我被告知不支持 jdk 17。但我真的不想降级，因为这可能会破坏我已经拥有和使用的其他东西。具体来说，这是我得到的错误:

我已经看过这个，但没有任何效果。 Gradle: Execution failed for task ':processDebugManifest'

Answer 1

所以我通过在我的系统上安装 JDK 16 解决了这个问题，一切都解决了并且运行良好。我不知道问题出在 Gradle 或 JDK 还是 react-native，但希望将来支持 jdk 17。

如果你有同样的问题，那么你可以去: jdk 16

1)下载并安装 JDK 16。

2)在你系统环境变量的PATH中加入你jdk的路径

3) 打开 cmd 并执行 java -version 你应该会看到类似的东西

java version "16.0.2" 2021-07-20
Java(TM) SE Runtime Environment (build 16.0.2+7-67)
Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing)
