问题描述

在我的Eclipse工作区中，我注意到.metadata文件夹不断增长。我应该定期删除这个文件夹吗？它的后果是什么？

In my Eclipse workspace I've noticed the .metadata folder keeps growing. Should I regularly delete this folder? What would be the consequences of it?

除此之外，.metadata文件夹包含什么信息？

Apart from that, what information does the .metadata folder contain?

推荐答案

删除所有 .metadata 文件夹将删除所有您的

Deleting all the .metadata folder would remove all your project references from your workspace.

如果您的项目实际上完全存储在工作区（即其源存储在默认工作空间路径中），那么您也将失去您的项目内容 - 这更糟糕的是，我可以重新导入它们。

If your project is actually stored completely in the workspace (i.e. its sources are stored in the default workspace path), you would also lose your project contents as well - which is worse since you wouldn't be able to re-import them.

我总是建议将Eclipse项目及其来源与工作区分开。

请参见 a href =https://stackoverflow.com/questions/2637735/what-is-src-directory-created-by-eclipse/2637787#2637787> Eclipse创建的src目录是什么？ 。

这样的设置特定于您的项目的项目将保存在您的项目中（在 .settings 目录），而不在工作空间中。

另外，您需要< href =https://stackoverflow.com/questions/452571/where-are-the-external-tools-launch-configurations-in-eclipse>还可以在您的项目中移动启动器定义。

I always recommend to keep your Eclipse project and its sources separate from the workspace.
See "What is "src" directory created by Eclipse?".
That way, the settings specific to your projects are saved within your project (in the .settings directory), and not in the workspace.
Also, you need to move your launcher definitions in your project as well.

在该配置中，您可以删除工作空间而不会受到很大的损害，只需将项目重新导入到新的工作区。

In that configuration, you can delete a workspace without much damage and simply re-import your project into a new workspace.
