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中有以下错误：

!MESSAGE Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Buddha'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

我已经尝试了几次，提取到不同的位置和不同的工作区，但我面临同样的错误。
我的发展受阻。任何帮助表示赞赏。
