Eclipse: JAVA_HOME not set
提问by En-Motion
The system cannot find the path specified.
JAVA HOME is not set correctly.
I am getting the following error when I try to run web server in Eclipse:
当我尝试在 Eclipse 中运行 Web 服务器时出现以下错误：
The system cannot find the path specified. JAVA HOME is not set correctly.
该系统找不到指定的路径。JAVA HOME 设置不正确。
But checking my env variables they look correct:
但是检查我的 env 变量，它们看起来是正确的：
echo %JAVA_HOME%
C:\Program Files (x86)\Java\jdk1.8.0_101
echo %PATH%
C:\ProgramData\Oracle\Java\javapath;c:\windows\system32;c:\windows;c:\windows\system32\wbem;c:\windows\system32\windowspowershell\v1.0\;C:\Program Files\Git\cmd;C:\HashiCorp\Vagrant\bin;C:\Installation;C:\Program Files (x86)\Brackets\command;C:\Program Files (x86)\Java\jdk1.8.0_101\bin;C:\ProgramData\Oracle\Java\javapath;c:\windows\system32;c:\windows;c:\windows\system32\wbem;c:\windows\system32\windowspowershell\v1.0\;C:\Program Files\Git\cmd;C:\HashiCorp\Vagrant\bin;C:\Installation;C:\Program Files (x86)\Brackets\command;C:\Program Files (x86)\Java\jdk1.8.0_101\bin;C:\ProgramData\Oracle\Java\javapath;c:\windows\system32;c:\windows;c:\windows\system32\wbem;c:\windows\system32\windowspowershell\v1.0\;C:\Program Files\Git\cmd;C:\HashiCorp\Vagrant\bin;C:\Installation;C:\Program Files (x86)\Brackets\command;
Is there something else I'm missing?
还有什么我想念的吗？

Check for system environment variables and user environment variables... seems like eclipse is taking variables from different environment..
检查系统环境变量和用户环境变量......似乎eclipse正在从不同的环境中获取变量..
If problem persist then set the JAVA_HOME in eclipse to tell eclipse explicitly where java is installed in the system. To set JAVA_HOME in eclispe few options given below.
如果问题仍然存在，则在 eclipse 中设置 JAVA_HOME 以明确告诉 eclipse java 在系统中的安装位置。要在 eclispe 中设置 JAVA_HOME，下面给出了几个选项。
To set JAVA_HOME in eclipse navigate to windows menu -> preferences -> Add runtime variables
要在 Eclipse 中设置 JAVA_HOME，请导航到 Windows 菜单 -> 首选项 -> 添加运行时变量
OR
或者
Navigate to Run menu -> External Tools configurations -> Navigate to environment tab -> Add JAVA_HOME variable and it's path as it's value to set environment variable in eclipse.
导航到运行菜单 -> 外部工具配置 -> 导航到环境选项卡 -> 添加 JAVA_HOME 变量及其路径作为在 eclipse 中设置环境变量的值。

actually the path/classpath/any setting is on "Administrator" privilege and will NOT be accessed if eclipse is started directly.
right click on eclipse.exe and select "Run As Administrator".
hope it works
实际上，路径/类路径/任何设置都具有“管理员”权限，如果直接启动 eclipse，则不会被访问。右键单击 eclipse.exe 并选择“以管理员身份运行”。
希望它有效
