Kotlin在Java安装中找不到所需的JDK工具

当运行./gradlew clean build时，我得到以下消息：

> Task :compileKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Kotlin could not find the required JDK tools in the Java installation '/usr/lib/jvm/java-8-openjdk-amd64/jre' used by Gradle. Make sure Gradle is running on a JDK, not JRE.

我已经安装了JDK，JAVA_HOME也设置正确，update-alternatives也是。 

# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

# update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status

  3            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode

以下是启用堆栈跟踪的 Gradle 构建：

所以从我看到的情况来看，它在搜索tools.jar时失败了——而我已经将其放在/usr/lib/jvm/default-java/lib下，因为配置路径是JDK。

我的gradle.build文件如下：

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.11'
}

ext {
    ktorVersion = "1.1.2"
}

group 'com.example'
version '1.0-SNAPSHOT'

repositories {
    jcenter()
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "io.ktor:ktor-server-netty:$ktorVersion"
    implementation "io.ktor:ktor-jackson:$ktorVersion"
    implementation "io.ktor:ktor-freemarker:$ktorVersion"
    implementation "io.ktor:ktor-auth:$ktorVersion"
    implementation "ch.qos.logback:logback-classic:1.2.3"
    implementation 'io.github.microutils:kotlin-logging:1.6.22'
    implementation 'org.koin:koin-ktor:2.0.0-beta-3'
    implementation 'org.litote.kmongo:kmongo-coroutine:3.10.0'
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

我真的不知所措，希望能得到些帮助。

如果需要更多信息，请让我知道，我会尽力提供。

你解决了吗？因为我已经在和它斗争了两天，还是搞不清楚问题出在哪里。 - redCuckoo
答案就在错误信息中！“确保Gradle在JDK上运行，而不是JRE。” JAVA_HOME必须指向JDK路径，而错误信息显示您的JAVA_HOME指向JRE。请参见https://dev59.com/Q-k5XIcBkEYKwwoY593M#63576967。 - Christian Davén

我通过删除一种Java版本来解决了这个问题。
我有两种Java，如下图所示。
但是当我执行./gradlew clean assembleRelease时出现错误，提醒我可能问题与我使用的JDK有关。
然后，我发现两种Java的home目录内容不同。左边是我从Oracle下载的。
因此，我尝试通过删除第一个Java的home目录（首先压缩文件夹进行复制）来修复它。
它奏效了！

我在使用open jdk 8时遇到了这个问题，切换到open jdk 11后问题得到解决。

export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64/"

如果您正在使用Mac，诀窍是安装来自Oracle的JDK，他们现在正在更改许可证政策，因此显然它不再完全免费用于商业用途。话虽如此，一旦安装完成，您可以在MAC上找到JDK，路径为：/Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home。如果你打开gradle.properties文件，你可以插入这一行内容：org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home. 重启Android Studio，选择Android设备，它应该能够正常工作。有趣的是，如果你在Finder中导航到该文件夹，然后将文件夹拖到TextEdit或VIM中的gradle.properties文件中，路径就会神奇地显示出来。我已经使用Mac超过10年了，在这个新的尝试进入Android Studio期间才发现了它。它对于我来说很有效。感谢Stack Overflow社区，它是任何应用程序开发人员工具包的重要部分。

在我的情况下，使用系统范围内安装的工具gradle而不是项目工具./gradlew能够运作。也就是说，我运行gradle ...而不是./gradlew ...。如果您的机器上安装了gradle，它应该被正确配置并知道Java在哪里。
请注意，我使用的是macOS，关于Linux和Windows，我不确定，但我认为应该是相同的。

我在这方面遇到了很多困难（MAC OS Monterey）。

但现在对我有效的方法是

  1. 从Oracle网站安装JDK 8。（需要登录）
  2. 在gradle.properties中添加org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_331.jdk/Contents/Home （jdk1.8.0_331.jdk是我的jdk文件夹名称，如果您有其他版本，则必须使用您自己的版本/文件夹名称。）
  3. 我在项目的android文件夹根目录下创建了一个名为local.properties的文件。 在那里，我添加了一行sdk.dir = /Users/USERNAME/Library/Android/sdk USERNAME应该是您的mac用户名。

我尝试在终端中将其声明为home变量，但由于某种原因它不起作用。但通过步骤2告诉gradle.properties可以解决问题 :)

它一直给我报错 FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:compileDebugKotlin'. > Kotlin could not find the required JDK tools in the Java installation 'C:\Program Files\Java\jre1.8.0_281' used by Gradle. Make sure Gradle is running on a JDK, not JRE

我通过下载并安装Java SE Development Kit 8解决了这个问题， 安装后在路径C:\Program Files\Java\jdk1.8.0_281中创建了文件夹。

在Ubuntu 20.04上，这对我有效：
sudo apt install default-jdk

在我的情况下，我的实验室有Windows 7、Visual Studio、Android Studio和Flutter环境。当我运行开始调试时，出现了同样的问题。

为了解决这个问题，

首先，在Visual Studio的扩展中使用扩展程序安装Java Extension Pack。

第二，按照Java Extension Pack的要求，在配置运行屏幕上需要JDK 11。

第三，下载并安装JDK（Java开发工具包）11。

第四，在安装过程中，您必须检查路径设置。也许，路径没有自动设置。您必须检查并设置路径。

如果您正确设置和安装，它将自动显示在系统环境变量中，名称为JAVA_HOME，而不是用户变量。

再次运行主要的Dart，您可以正确地看到模拟器。

对我而言，我的机器上只安装了 JRE（Java运行环境）。设置

JAVA_HOME= C:\Program Files\Android\Android Studio\jre

对我有效
