第一个反应本机应用程序：任务：app：processDebugMainManifest FAILED

Question

问题

我已按照 https://reactnative.dev/docs/environment-setup 中指定的说明进行操作，但巧克力除外，因为我已经有节点等。但我无法构建我的应用程序以达到模拟器上的输出 RN 样板（第 2 步：在文档中）在 npx react-native run-android 之后。我已经搜索了很多小时来修复，但我没有得到任何结果，这变得非常令人沮丧。下面我附上了相关的输出。

提前感谢您的帮助。我才刚开始，所以如果我需要进一步提问以完全理解问题，请原谅我。

Answer 2

在 JDK 17 上对我有用的东西，对 JDK 16 也适用：

将以下行添加到项目中的./android/gradle.properties 文件中：

org.gradle.jvmargs=--add-opens java.base/java.io=ALL-UNNAMED

如果现有 Gradle 实例已经在运行，您可能需要停止这些实例，最简单的方法是重新启动您的操作系统。

就是这样！

到目前为止，我在使用带有 React Native 的 JDK 17 时没有遇到任何其他问题

Answer 3

在你的命令行中试试这个命令

cd android && gradlew clean

然后

cd ..
react-native run-android

Answer 4

我遇到了同样的问题（JDK 16）并修复了它：

• npx react-native start
• 打开 android studio 并让它清理项目
• 在 android studio 中运行应用

Answer 5

如前所述，今天在 Mac 上遇到了同样的问题，降级到 Java 15。

我使用 brew install --cask adoptopenjdk 安装了 java，今天我决定升级我安装的应用程序...它自动更新到 java 16，这破坏了 react native 构建。

这就是我对 brew 所做的：

brew uninstall adoptopenjdk
brew install --cask adoptopenjdk/openjdk/adoptopenjdk15

仅供参考，这是我安装和工作的版本：

% java --version
openjdk 15.0.2 2021-01-19
OpenJDK Runtime Environment AdoptOpenJDK (build 15.0.2+7)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 15.0.2+7, mixed mode, sharing)

Answer 6

对于您的问题，就像其他人已经告诉您的那样，正确的解决方案是将您的 JDK 降级到 15 或更低。

你不需要取消它，你可以简单地决定切换它。

在终端输入 /usr/libexec/java_home -V 以检查您当前的 java 版本

如果您没有找到合适的（在这种情况下为 https://www.oracle.com/java/technologies/javase-downloads.html

然后在您的终端中（在您的项目内部也可以）您应该输入 export JAVA_HOME=`/usr/libexec/java_home -v 15.0.2` （或您的正确版本！）

检查您是否使用了正确的版本：java -versioncommand，如果是，您应该能够在 android 模拟器上运行！

要将此 JDK 版本设为默认版本，您可以通过在终端中键入来更改 bash 文件配置文件

open ~/.bash_profile

然后添加

# SWITCH TO JAVA VERSION 15.0.2

export JAVA_HOME=`/usr/libexec/java_home -v 15.0.2

Answer 7

这是 JDK 16 的问题，请将您的 JDK 降级到较低版本并在 vi ~./bash 配置文件中设置相同的 JAVA_HOME 路径

Answer 8

我认为您已将 Java 更新到版本 16。请将 Java 降级到版本
