Gradle Could not find tools.jar
提问by Fishy
I am trying to make a game with LibGdx. I love it! It is sooo simple and a lot better than JME3 and LWJGL. But trying to package it I am having an error. Here is an image of the gui for Gradle: http://prntscr.com/845kyxand here is a the full debug error: http://pastebin.com/ugdfySg1Now I don't know how to debug those errors and what not, so I hope someone can help. I have also tried to re-create the entire project, and make it a eclipse valid project, instead of just Gradle. None of that worked.
我正在尝试使用 LibGdx 制作游戏。我喜欢它！它非常简单，而且比 JME3 和 LWJGL 好很多。但是尝试打包时出现错误。这是 Gradle 的 gui 图像：http: //prntscr.com/845kyx，这是完整的调试错误：http: //pastebin.com/ugdfySg1现在我不知道如何调试这些错误以及什么没有，所以我希望有人可以提供帮助。我还尝试重新创建整个项目，并使其成为 Eclipse 有效项目，而不仅仅是 Gradle。这些都没有奏效。

You have to set the system property "java.home" and the environment variable JAVA_HOME to a valid JDK.
您必须将系统属性“java.home”和环境变量 JAVA_HOME 设置为有效的 JDK。
To set the environment variable run:
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
要设置环境变量运行：
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

I have a file called gradle.propertiesat the root of my project with the following property:
我有一个gradle.properties在项目根目录下调用的文件，它具有以下属性：
org.gradle.java.home=C:\Program Files\Java\jdk1.8.0_74
org.gradle.java.homeneeds to point to a valid JDK location.
org.gradle.java.home需要指向一个有效的 JDK 位置。
Without this file, I get the same error (Could not find tools.jar). With the file present, this is no longer an issue.
如果没有这个文件，我会得到同样的错误（找不到 tools.jar）。有了文件，这不再是问题。

For me was solution this:
对我来说是这样的解决方案：
yum install java-1.8.0-openjdk-devel
Or for newer CentOS/Fedora/RHEL versions:
或者对于较新的 CentOS/Fedora/RHEL 版本：
dnf install java-devel

If we already have a lot of different distro answers I might as well add the Arch answer:
如果我们已经有很多不同的发行版答案，我不妨添加 Arch 答案：
sudo pacman -S jdk8-openjdk
