【问题描述】：

我想问一下以下错误。所以一年前我一直在开发一个小型 BLE 应用程序并成功地实现了它。我没有将它推送到 Google Play 商店，而是通过 USB 以某种方式将它安装在 android 上。

但是，现在我需要让它重新启动并运行，但我面临着过多的错误。

The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build.
This might happen in subprojects that apply the Kotlin plugins with the Gradle 'plugins  ... ' DSL if they specify explicit versions, even if the versions are equal.
Please add the Kotlin plugin to the common parent project or the root project, then remove the versions in the subprojects.
If the parent project does not need the plugin, add 'apply false' to the plugin line.
See: https://docs.gradle.org/current/userguide/plugins.html#sec:subprojects_plugins_dsl
The Kotlin plugin was loaded in the following projects: ':expo-error-recovery', ':expo-permissions'

【参考方案1】：

您好像没有安装 JDK。

如果您使用的是 Mac，请使用以下命令通过 brew 安装它，或者按照文档了解如何在您的特定机器上安装

brew install --cask adoptopenjdk/openjdk/adoptopenjdk8

按照这个guide在windows上安装

请参阅文档https://reactnative.dev/docs/_getting-started-macos-android#installing-dependencies

【讨论】：

幸运儿，非常感谢！我一点也不知道没有 jdk 可能是问题所在，尤其是当我清楚地记得在某个时候安装它时。尽管如此，您的解决方案是 100% 正确的，而且您肯定为我节省了很多时间！请问你是怎么发现的？它没有在任何地方提及。该错误甚至指出了反应库或已弃用的 Gradle，但没有提及缺少 jdk。

太棒了！我很高兴它奏效了。基本上做了一些谷歌搜索并缩小范围。
