Kotlin在Java安装中找不到所需的JDK工具

Krz*_*zko 6 ubuntu gradle kotlin gradlew

运行时，./gradlew clean build我收到以下消息：

> Task :compileKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.

我有JDK，JAVA_HOME设置正确，也是如此update-alternatives。

最后，我重建了我的项目 ( react-native run-android) 并且一切正常。

我不确定删除 JRE 是最好的解决方案，因为您可能需要 JRE 来处理其他事情，但我没有注意到任何不良影响。此外，看来我已经安装了 JDK，这可能不适用于所有 Mac 用户。

由于 Stack Overflow 上没有任何好的答案可以解决 MacOS 上的这个问题，我想我会在这里发布我的解决方案。

android studio 也提供 jdk。如果你指定 jdk 如下，它会成功

在 MacOS 更新到 Big Sur 之后，我看到了与上面 Tom Aranda 相同的问题。经过进一步调查，我遇到了这个 SO post，这让我找到了这个雷达。我不高兴按照 Tom 的回答删除 JRE，因此我已经使用其他帖子中的详细信息解决了我自己的安装问题.....

我之前的声明JAVA_HOME是在~/.zshrc作为

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

但 Big Sur 似乎也将默认 JRE 版本更新为 1.8。所以我的 JAVA_HOME 需要更精确的过滤。

根据雷达和其他 SO 帖子中的详细信息，我还需要确保在再次导出之前未设置任何现有导出的 JAVA_HOME，因此我的新条目~/.zshrc现在已成为

终端重新启动后，我以前失败的gradlew命令现在可以像以前一样运行。

我遇到了完全相同的问题。我通过安装解决了它OpenJDK 8 JDK。我的机器正在运行，centos所以这是我的安装命令

sudo yum install java-1.8.0-openjdk-devel.

我从这篇文章中了解到有两个不同的 Java 包，Java 运行时环境 (JRE) 和 Java 开发工具包 (JDK)。JRE 用于运行 Java 程序，JDK 用于开发 Java 应用程序。我只安装了 JRE，但没有安装 JDK。安装JDK后，我的构建运行成功

它被设置为/usr/lib/jvm/java-8-openjdk-amd64/jre.

应该将 JAVA_HOME 设置为/usr/lib/jvm/java-8-openjdk-amd64/

如果您的操作系统是 Ubuntu，请通过 suer 安装 openjdk jdksudo apt-get install openjdk-8-jdk

sudo apt install openjdk-8-jre-headless 将安装jre，而不是jdk

在 BIG SUR 上，收到此错误的人可能已经安装了自定义 Java。使用以下命令删除它

根据提供的数据，确保java该环境路径中。但是，它不能确认JAVA_HOME是否设置为JDK目录。你肯定JAVA_HOME没有被设置为/usr/lib/jvm/java-8-openjdk-amd64/jre代替/usr/lib/jvm/java-8-openjdk-amd64或/usr/lib/jvm/default-java？

因为，如果JAVA_HOME是一套，然后gradlew将忽略java二进制文件的路径和执行$JAVA_HOME/bin/java这反过来将可用System.getProperty("java.home")在这个记录异常（见jarSearchingUtil.Kt）

否则，您可以尝试直接在gradlew文件中声明JAVA_HOME

在更新到 Mac Big Sur 之前一切都工作正常，我在本地计算机上使用 Jenkins 和 Fastlane 'sh Fastlane beta' 进行 Firebase 分发。这是一个颤振项目。

我刚刚添加org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home到 gradle.properties 中。这解决了我的问题。
