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

问题描述

我已将我的 JAVA_HOME 设置为 /usr/lib/jvm/java-7-oracle，其中包含有效的 JVM，但 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让 gradle 使用我的有效 JAVA_HOME?

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

注意:我的 JAVA_HOME 是由 ~/.bashrc 使用 export JAVA_HOME="/usr/lib/jvm/java-7- 设置的神谕"

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

推荐答案

这是一个很常见的问题.只需转到您的 gradle 主目录和 bin，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 gradle 脚本，我现在在 Windows 机器上，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
