Gradle does not recognize the JAVA_HOME I have set
提问by Nicolas Raoul
I have set my JAVA_HOMEto /usr/lib/jvm/java-7-oracle, which contains a valid JVM, but gradle insists on using /usr/lib/jvm/default-javaand complains about JAVA_HOME:
我已将 my 设置JAVA_HOME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：
$ 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.
How can I fix this and have gradle use my valid JAVA_HOME?
我该如何解决这个问题并让 gradle 使用我的 valid JAVA_HOME？
Note: My JAVA_HOMEis set by ~/.bashrcusing export JAVA_HOME="/usr/lib/jvm/java-7-oracle"
注意：我JAVA_HOME是通过~/.bashrc使用设置的export JAVA_HOME="/usr/lib/jvm/java-7-oracle"

it is quite common issue. Just go to your gradle home directory and bin, for example:
这是很常见的问题。只需转到您的 gradle 主目录bin，例如：
/home/user/gradle-2.0/bin
and there you should have gradle script, I am on a Windows machine now so I have gradle.bat, probably you will have gradle.shor something like this. In that file, find the line:
在那里你应该有 gradle 脚本，我现在在一台 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：
set JAVA_HOME=%JAVA_HOME:"=%
or as I can see you are on linux so there will be "export" and change it to your java home directory for example:
或者如我所见，您在 linux 上，因此将“导出”并将其更改为您的 java 主目录，例如：
export JAVA_HOME=/usr/lib/jvm/java-7-oracle

If on windows, also make changes to JAVA_EXE and add your path
如果在 Windows 上，还要更改 JAVA_EXE 并添加您的路径
set JAVA_EXE=C:\yourpath\bin\java.exe
