Kotlin在Java安装中找不到所需的JDK工具

ubuntugradlekotlingradlew
106

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 '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

我在 MacOS（Big Sur）中解决了一个类似的问题。我的情况是运行 React Native 项目并在尝试构建 Android 时出现以下错误：

* What went wrong:
Execution failed for task ':bugsnag_react-native:compileDebugKotlin'.
> Kotlin could not find the required JDK tools in the Java installation '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home' used by G
radle. Make sure Gradle is running on a JDK, not JRE.

我遵循这篇文章来卸载MacOS上的JRE。稍作修改以使该过程可逆，以下是步骤：

cd /Library/Internet\ Plug-Ins/
mv JavaAppletPlugin.plugin DELETED-JavaAppletPlugin.plugin
cd /Library/PreferencePanes/
mv JavaControlPanel.prefPane DELETED-JavaControlPanel.prefPane

当你收到“Permission denied”时，在命令前使用“sudo”。

然后我清空了我的Gradle文件夹。我不知道这是否必要，但对我起作用了：

rm -rf ~/.gradle

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

我不确定删除JRE是最好的解决方法，因为您可能需要JRE进行其他操作，但我没有注意到任何不良影响。此外，似乎我已经安装了JDK，而这并非所有Mac用户都是如此。

由于在Stack Overflow上没有很好的答案来解决这个问题，所以我想在这里发布我的解决方案。

这对我有用，正如在MacOS Big Sur中所提到的。我还省略了清除gradle文件夹的步骤。感谢这个！ - srinij
对我来说，“rm -rf ~/.gradle”是不必要的，因为我正在使用Android Studio和本地代码，我只是升级到了Big Sur，然后遇到了这个问题。 - dicarlomagnus

Android Studio也提供了JDK。 如果您按照下面指定的方式指定JDK，它将成功。

export PATH=$PATH:/Applications/"Android Studio.app"/Contents/jre/jdk/Contents/Home/bin
export JAVA_HOME=/Applications/"Android Studio.app"/Contents/jre/jdk/Contents/Home

这应该是被接受的答案，不需要安装另一个JVM。 - M. Reza Nasirloo

这个之前对我来说是可以工作的，但是在 Android Studio 更新后出现了无效路径的错误。我需要将第二行更改为 export JAVA_HOME=/Applications/"Android Studio.app"/Contents/jre/Contents/Home。 - James
这对我有用，如果有人确定他有Java，那么这就是正确的答案。 - M.Nasri
这绝对是针对Mac的答案，带有@James的更新。 - maddesa

在升级到Big Sur操作系统后，我遇到了与Tom Aranda先生相同的问题。经过进一步调查，我发现了这个SO帖子，这让我找到了这个radar。我不想像Tom的答案那样移除JRE，所以我通过其他帖子中的详细信息解决了自己的安装问题......

我之前在~/.zshrc中声明的JAVA_HOME如下：

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

但是，Big Sur似乎已经将默认的JRE版本更新为1.8版本。因此，我的JAVA_HOME需要更精确地进行过滤。

% /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.251.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_241 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

现在我导出为：

export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_241`

现在这并不理想，因为下次我更新JDK时它就会出问题。

根据radar和其他SO帖子中的细节，我还需要确保在重新导出之前取消任何现有的导出的JAVA_HOME，因此我的~/.zshrc中的新条目现在变成了：

unset JAVA_HOME;export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_241`

在终端重新启动后，我之前失败的gradlew命令现在可以像以前一样运行。

对我来说，这感觉更好，因为我没有删除任何库，并且只影响了从我的终端命令中指定的java home。遗憾的是，我需要指定精确版本，因为这将在未来的某个时候发生故障。

在BIG SUR上，遇到这个错误的人可能安装了自定义Java。请使用以下方法将其移除

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

在此之后，取消设置任何自定义的JAVA_HOME，并从您的shell中删除它，然后它应该可以正常工作。

这对我有用。我还从Oracle下载并安装了所需的JDK。直到我运行了上面的命令，我的命令仍然无法正常工作。 - speedynomads
谢谢，伙计！对我也管用！ - provisota
我也一样 :P 非常感谢！ - Ihar Paliashchuk
谢谢。我不得不删除自定义安装并设置Java主目录以使用Big Sur中的Java 8。 - giri-sh

在Windows上，将此添加到gradle.properties中，并附上您的jdk版本

org.gradle.java.home=C:\\Program Files\\Java\\jdk1.8.0_102

这是特定于Windows和某个Java版本的。 - Vegard Stikbakke
谢谢。我不记得我使用的Java版本是什么，但这解决了我的问题。 - kosher
非常感谢，兄弟...它像魔法一样工作了，你救了我的一天。 - Partha Paul

我遇到了完全相同的问题。我通过安装OpenJDK 8 JDK解决了这个问题。我的机器运行着centos，这是我的安装命令

sudo yum install java-1.8.0-openjdk-devel。

我从这篇文章中学到了有两种不同的Java软件包，Java Runtime Environment (JRE) 和 Java Development Kit (JDK)。 JRE用于运行Java程序，而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，我的构建顺利运行了。

@IgorGanapolsky，yum是CentOS的软件包管理器。 - Chris

> 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.

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sudo apt-get install openjdk-8-jdk安装openjdk jdk。

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

同时，在安装JDK之前，卸载JRE版本可能会有所帮助，因为它们共享相同的父路径。我曾经尝试过在不删除JRE的情况下安装JDK，并未解决问题。 - Katherine Chen

1. 安装Java

https://www.oracle.com/java/technologies/downloads/ enter image description here

2. 查找Java路径

/usr/libexec/java_home -V

enter image description here

3. 设置MAC环境变量

使用vim编辑 ~/.bash_profile 文件：

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_321.jdk/Contents/Home
export CLASSPAHT=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH:

执行命令：source ~/.bash_profile

4. 验证

@B-X24EQ05P-1937 jdk1.8.0_321.jdk % java -version         
java version "1.8.0_321"
Java(TM) SE Runtime Environment (build 1.8.0_321-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.321-b07, mixed mode)
我不得不从官方网站下载并安装正确的Java SDK，这解决了我的问题。 - Nasir

根据提供的数据，可以确定环境路径中有 java。但是，这并不能确认 JAVA_HOME 是否设置为 JDK 目录。您确定 JAVA_HOME 没有被设置为 /usr/lib/jvm/java-8-openjdk-amd64/jre 而不是 /usr/lib/jvm/java-8-openjdk-amd64 或者 /usr/lib/jvm/default-java 吗？
因为，如果已经设置了 JAVA_HOME，那么 gradlew 将会忽略环境路径中 java 的二进制文件，并执行 $JAVA_HOME/bin/java，后者将在 System.getProperty("java.home") 中记录，而该值在此异常中被记录下来（请参见 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，所有东西都正常运行。我在本地机器上使用了Jenkins和Fastlane 'sh Fastlane beta'来进行Firebase分发。这是一个Flutter项目。

我只是在gradle.properties中添加了org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home，这解决了我的问题。

如果这不起作用，请提供已安装Java的绝对路径：/Library/Java/JavaVirtualMachines/jdk1.8.0_321.jdk/Contents/Home - Harsh Patel
