Eclipse工作区中的.metadata文件夹是什么？ [英] What is the .metadata folder in Eclipse workspace?

问题描述

我的工作空间文件夹包含一个名为.metadata的隐藏文件夹。定期备份此文件夹很重要吗？

My "workspace" folder includes a hidden folder called ".metadata". Is it important to backup this folder regularly?

推荐答案

.metadata 文件夹是Eclipse插件可以保存任何要保存的信息。这将包括您的首选项设置和Java插件快速查找类和方法的索引。

The .metadata folder is an area where Eclipse plug-ins can save any information they want to save. This will include things like your preference setting and the index the Java plug-in uses to find classes and methods quickly.

它还包括。日志文件，其中Eclipse记录错误。

It also includes the .log file where Eclipse logs errors.

正好存储的内容取决于您安装的插件（我的一个插件在.metadata中有一个数据库），所以最好备份它（和项目一起）。

Exactly what is stored there depends on the plug-ins you have installed (one of my plug-ins has a database in the .metadata) so it is a good idea to back it up (along with the projects).
