Gradle不能识别我设置的JAVA_HOME [英] Gradle does not recognize the JAVA_HOME I have set

问题描述

我已将 JAVA_HOME 设置为 / usr / lib / jvm / java-7-oracle ，其中包含一个有效的JVM，但是gradle坚持使用 / usr / lib / jvm / default-java 并抱怨 JAVA_HOME ：

I have set my JAVA_HOME to /usr/lib/jvm/java-7-oracle, which contains a valid JVM, but gradle insists on using /usr/lib/jvm/default-java and complains about JAVA_HOME:

$ echo $JAVA_HOME 
/usr/lib/jvm/java-7-oracle
$ ls $JAVA_HOME
bin  COPYRIGHT  db  include  jre  lib  LICENSE  man  README.html  release  src.zip  THIRDPARTYLICENSEREADME-JAVAFX.txt  THIRDPARTYLICENSEREADME.txt
$ gradle assemble

ERROR: JAVA_HOME is set to an invalid directory: /usr/lib/jvm/default-java

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

如何解决这个问题，并逐渐使用我有效的 JAVA_HOME ？

How can I fix this and have gradle use my valid JAVA_HOME?

注意：我的 JAVA_HOME 由〜 /.bashrc 使用 export JAVA_HOME =/ usr / lib / jvm / java-7-oracle

Note: My JAVA_HOME is set by ~/.bashrc using export JAVA_HOME="/usr/lib/jvm/java-7-oracle"

推荐答案

这是很常见的问题。例如：

it is quite common issue. Just go to your gradle home directory and bin, for example:

/home/user/gradle-2.0/bin

你应该有毕业生脚本，我在现在一台Windows机器，所以我有 gradle.bat ，可能你会有 gradle.sh 或类似的东西。在该文件中，找到以下行：

and there you should have gradle script, I am on a Windows machine now so I have gradle.bat, probably you will have gradle.sh or something like this. In that file, find the line:

set JAVA_HOME=%JAVA_HOME:"=%

或者我可以看到你在linux上，所以会有导出，并将其更改为你的java主目录，例如：

or as I can see you are on linux so there will be "export" and change it to your java home directory for example:

export JAVA_HOME=/usr/lib/jvm/java-7-oracle
