I'm trying to set my JAVA_HOME path to use my javac.exe?
提问by Joseph Safwat
I'm on Windows 7 and I'm trying to set my JAVA_HOMEpath to use PhoneGap on android, when i create a project using the command line "cmd" it tells me that it can't find javac.exe? although i'm sure that I've set the variable right
我在 Windows 7 上，我正在尝试设置JAVA_HOME在 android 上使用 PhoneGap 的路径，当我使用命令行“cmd”创建项目时，它告诉我它找不到 javac.exe？虽然我确定我已经正确设置了变量
here's my stuff:
这是我的东西：
Variable name: JAVA_HOME
Variable value: C:\Progra~1\Java\jdk1.7.0_17\bin
(I've also tried to use: C:\Progra~1\Java\jdk1.7.0_17\bin\javac.exe)
My javac.exe location on my laptop C:\Program Files\Java\jdk1.7.0_17\bin\javac.exe
我的笔记本电脑上的 javac.exe 位置 C:\Program Files\Java\jdk1.7.0_17\bin\javac.exe
and it still tells me that it can't locate the javac.exe
它仍然告诉我它无法找到 javac.exe
What I type to create the project and i meet this problem is this:
我输入的内容来创建项目，我遇到这个问题是这样的：
C:\Users\user>cd C:\Users\user\Desktop\phonegap-2.8.1\lib\android\bin
C:\Users\user\Desktop\phonegap-2.8.1\lib\android\bin>create.bat
Cannot locate javac.exe using the PATH environment variable.
Retry after adding directory containing javac.exe to the PATH variable.
Remember to open a new command window after updating the PATH variable.
Visit http://java.oracle.com if you need to install Java (JDK).
Also, i've tries restarting the windows and closing the command prompt and redownloading the JDK.
此外，我尝试重新启动 Windows 并关闭命令提示符并重新下载 JDK。
Thank You.
谢谢。

cmdis using the values from the PATHvariable to locate javac:
cmd正在使用PATH变量中的值来定位javac：
set "PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_17\bin"
For other softwares (Tomcat, Maven, etc.) JAVA_HOMEmust indicate the root of your JDK :
其他软件（Tomcat、Maven等）JAVA_HOME必须注明你的JDK根目录：
set "JAVA_HOME=C:\Program Files\Java\jdk1.7.0_17\"
No need to restart Windows. When using setthe changes are taken immediately.
无需重新启动 Windows。使用时set立即进行更改。
If you choose to modify those variables in the Control Panel, you have to close and relaunch cmdfor the changes to take effect.
如果您选择在控制面板中修改这些变量，则必须关闭并重新启动cmd以使更改生效。

I already had this error when I tried to create a new phonegap project for android but unfortunately I don't remember how exactly I have fixed this.
当我尝试为 android 创建一个新的 phonegap 项目时，我已经遇到了这个错误，但不幸的是我不记得我是如何解决这个问题的。
I don't know if you have followed the phonegap documentation so here is the link : new project, especially the part 3B (be careful about ;in your PATH).
If you don't know what to do now, maybe you should do it again step by step.
我不知道您是否遵循了 phonegap 文档，所以这里是链接：新项目，尤其是 3B 部分（;在您的PATH. 如果你现在不知道该做什么，也许你应该一步一步地再做一次。

May be a little old, but since this is the first goolge result, I might as well add a little something.
可能有点老了，不过既然是第一个goolge结果，还是补充一点吧。
You need to create the JAVA_HOME variable AND edit the PATH variable, adding ;%JAVA_HOME%\bin(with a ;) so cmd and some other apps can actually use javac and the rest of the tools
您需要创建 JAVA_HOME 变量并编辑 PATH 变量，添加;%JAVA_HOME%\bin（带有 ;）以便 cmd 和其他一些应用程序可以实际使用 javac 和其余工具
