【问题描述】：
我已经从 Eclipse 下载位置下载了最新版本的 Eclipse eclipse-jee-2019-09-R-win32-x86_64.zip。提取它并创建一个新项目。
我在 eclipse 中遇到以下错误：
环境变量：
C:\Users\User>java -version

not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and

我已经尝试了几次，提取到不同的位置和不同的工作区，但我遇到了同样的错误。
我的发展受阻。任何帮助表示赞赏。
【问题讨论】：
-
@Ambro-r 该特定错误只是一个警告。我刚刚设置了 HOME 变量。但这并不能解决我的问题。顺便说一句，以上两个链接都指向同一个问题。
-
尝试在 Window > Preferences: Java > Installed JREs 中删除并再次添加 Java 8 JDK (
C:\Program Files\Java\jdk1.8.0_202)。如果这不起作用，Java JDK 的安装可能会被破坏。 -
是的，重新安装了 JDK。重新启动了系统。只有这样它才开始工作。谢谢@Howlger
