设置JAVA_HOME时出错 [英] Error in setting JAVA_HOME

问题描述

我最近下载了Maven，并按照此页面上的说明进行操作。我已经在我的机器上安装了ant。
现在，如果我想验证Maven是否安装完好，它会给我一个JAVA_HOME设置不正确的错误，但同样适用于ANT。

I have recently downloaded Maven and followed the instructions given on this this page. I already have ant installed on my machine. Now, if I want to verify that Maven is installed perfectly or not it is giving me error that JAVA_HOME is not set correctly, but same works perfectly fine for ANT.

For Maven I tried :
1. open cmd
2. type mvn -version
3. Error appeared :
C:\Users\Admin>mvn -version

ERROR: JAVA_HOME is set to an invalid directory.
JAVA_HOME = "C:\Program Files\Java\jre7\bin"
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation

For ANT I tried and worked :
1. open cmd
2. type mvn -version
3. Apache Ant(TM) version 1.9.1 compiled on May 15 2013

我去了目录检查java.exe实际上是否存在于该目录中并且没有在那里。我检查了他们设置好的环境变量。我重新启动系统并再次检查但同样的问题。请告诉我我错过了什么。

I went to the directory to check that java.exe is actually there in that directory or not and it was there. I checked the environment variables they set fine. I restarted the system and checked again but same problem. Please let me know what am I missing.

推荐答案

JAVA_HOME应该指向jdk目录而不是指向jre目录。另外JAVA_HOME应该指向home jdk目录而不是jdk / bin目录。

JAVA_HOME should point to jdk directory and not to jre directory. Also JAVA_HOME should point to the home jdk directory and not to jdk/bin directory.

假设您在程序文件目录中安装了JDK，那么您需要设置JAVA_HOME像这样：

Assuming that you have JDK installed in your program files directory then you need to set the JAVA_HOME like this:

JAVA_HOME="C:\Program Files\Java\jdkxxx"

xxx是jdk版本
