JAVA_HOME variable
提问by Sapphire
I set my JAVA_HOME variable to point to the jdk and I added %JAVA_HOME%\bin to the Path variable. However, my ant script is not able to find the jdk. It's looking into the wrong folder for Java compiler. here's the error I'm getting.
我将 JAVA_HOME 变量设置为指向 jdk，并将 %JAVA_HOME%\bin 添加到 Path 变量中。但是，我的 ant 脚本无法找到 jdk。它正在查看 Java 编译器的错误文件夹。这是我得到的错误。
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to C:\Program Files\Java\jre6
com.sun.tools.javac.Main 不在类路径上。也许 JAVA_HOME 没有指向 JDK。目前设置为C:\Program Files\Java\jre6
I set my JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0
我设置了我的 JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0
What am I doing wrong? Please help!
我究竟做错了什么？请帮忙！

If your Java installation directory has a space in its path name, you should use the shortened path name (e.g. C:\Progra~1\Java\jre6) in the environment variable instead.
如果您的 Java 安装目录的路径名中有空格，您应该在环境变量中使用缩短的路径名（例如 C:\Progra~1\Java\jre6）。
- Progra~1 = 'Program Files'
- Progra~2 = 'Program Files(x86)'
- 程序~1 = '程序文件'
- 程序~2 = '程序文件（x86）'

When you want to use JAVA_HOME in your path variable it is recommended to use "%JAVA_HOME%\bin"instead of %JAVA_HOME%\bin.
当你想在你的路径变量使用JAVA_HOME建议使用"%JAVA_HOME%\bin"来代替%JAVA_HOME%\bin。
