Eclipse启动错误：A Java Runtime Environment(JRE) or Java Development Kit(JDK) must be available……

确保Jdk，Jre都安装完成并且环境变量配置无误的情况下，自动Ecplise报错如下：

A Java Runtime Environment (JRE) or Java Development Kit(JDK)
must be available in order to run Eclipse. No Java virtualmachine
was found after searching the following locations:
D:\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH

解决办法：

打开Eclipse根目录eclipse.ini文件，在最前面加上两行：

-vm
C:\Program Files\Java\jdk1.8.0_171\bin\javaw.exe

（这个是你安装的javaw.exe的绝对路径）
