步骤二、解压

将features和plugins解压到dropins目录，并重新打开eclipse。

方法二：

安装语言包
通过“帮助”>“安装新软件…”打开安装向导。
添加Babel p2存储库：https://download.eclipse.org/technology/babel/update-site/R0.18.2/2020-12/
选择/安装您选择的语言包
重新启动Eclipse，获得翻译的Eclipse使用语言包
如果您的操作系统的系统语言环境已经是您要用来启动Eclipse的语言，那么您所要做的就是正常启动Eclipse，并且将加载语言包。

如果系统语言环境为英语，并且您想以另一种语言启动Eclipse，则必须使用-nl命令行参数来启动Eclipse ：

eclipse.exe -nl fr
用您要使用的语言环境替换fr。有关更多详细信息，请参见“运行Eclipse”。另请参阅“教您的Eclipse讲本地语言”的Eclipse Corner文章，以获取更多有关如何以不同的语言（包括双向语言，如阿拉伯语）和不同的操作系统（如Linux和Mac OS X）启动Eclipse的更多示例。
