我如何告诉Gradle使用特定的JDK版本？ [英] How do I tell Gradle to use specific JDK version?

问题描述

场景：

• 我有一个使用gradle构建的应用程序


• 应用程序使用JavaFX

想要使用一个变量（定义为每个开发人员机器），它指向一个JDK的安装，它将用于构建整个应用程序/测试/ ...

我想过要有 gradle.properties 文件，定义变量。类似于

  JAVA_HOME_FOR_MY_PROJECT =<我想要的JDK的路径> 
  

我不想要的东西

• 点 JAVA_HOME 到所需的JDK

I可以忍受很多建议：

• 一个解决方案，它定义了一个系统环境变量，我可以在我的build.gradle脚本中检查


• 在gradle.properties中定义的变量
• 仅为构建上下文重写JAVA_HOME变量（类似于使用JAVA_HOME =< ;我的特殊JDK路径定义在其他地方定义> ）


• 其他我没想过的东西

问题：

• 如何连线一个变量（如何定义变量， c $ c> gradle.properties ，系统环境变量，...）到构建过程中？
  

我有多个JDK7可用，需要指向特殊版本（最低JDK_u版本）。

任何答案都是appr eciated，我感谢每一个提示正确的方向。

解决方案

两种方式

1. 在 .gradle 中的 gradle.properties 目录中的 HOME_DIRECTORY 设置 org.gradle.java.home = / path_to_jdk_directory


$ li $ build.gradle

  compileJava.options.fork = true 
 compileJava.options.forkOptions.executable = / path_to_javac

I can't figure out to get this working.

Scenario:

• I have an application built with gradle
• The application uses JavaFX

What I want

• Use a variable (defined per developer machine) which points to an installation of a JDK which will be used for building the whole application / tests / ...

I thought about having the gradle.properties file, defining the variable. Something like

JAVA_HOME_FOR_MY_PROJECT=<path to my desired JDK>

What I don't want

• point JAVA_HOME to the desired JDK

I could live with many suggestions:

• a solution that defines a system environment variable which I'm able to check in my build.gradle script
• a variable defined in gradle.properties
• overriding the JAVA_HOME variable only for the build context (something like use JAVA_HOME=<my special JDK path defined somewhere else defined>)
• something else I didn't think about

Question:

• How to wire a variable (how ever defined, as variable in the gradle.properties, system environment variable, ...) to the build process?

I have more than one JDK7 available and need to point to a special version (minimum JDK_u version).

Any answer is appreciated and I'm thankful for every hint to the right direction.

解决方案

Two ways

1. In gradle.properties in the .gradle directory in your HOME_DIRECTORY set org.gradle.java.home=/path_to_jdk_directory

2. In your build.gradle

   compileJava.options.fork = true
   compileJava.options.forkOptions.executable = /path_to_javac
