当Eclipse正在更新索引时，Eclipse会做什么？ [英] What is Eclipse doing when it says that it's updating indexes?

问题描述

当我加载一个工作区（对于Android Java开发），Eclipse在状态栏中说它正在更新索引。 进度选项卡报告它正在击中maven.org。

When I load up a workspace (for Android Java development), Eclipse says in the status bar that it's updating indexes. The Progress tab reports that it's hitting maven.org.

我在Maven上阅读 - 似乎是一个构建管理器。我不明白的是为什么我的Android工作区需要它，或者为什么它在云中的服务器。我需要吗？如果没有，我该如何安全地删除它？

I read up on Maven - seems like a build manager. What I don't understand is why my Android workspace needs it or why it's hitting the server in the cloud. Do I need it? If not, how do I safely remove it?

推荐答案

这是一个通用的步骤，当安装了m2e / m2eclipse（Maven集成为Eclipse）项目是否正在积极使用。

This is a general step that happens when m2e/m2eclipse (Maven integration for Eclipse) is installed, whether projects are actively using it or not.

可以通过Eclipse首选项禁用此步骤：Window / Preferences / Maven /启动时下载存储库索引更新。此选项位于主Maven首选项页面（而不是子页面）上。只需取消选中该框即可防止这种情况发生。

This step can be disabled through the Eclipse preferences: Window / Preferences / Maven / "Download repository index updates on startup". This option is on the main "Maven" preference page (not a child page). Just uncheck the box to prevent this from happening.

下载的文件是Maven中央存储库中可用的所有可用依赖项的索引，用于启用Maven的项目，允许他们在Eclipse UI中轻松选择和搜索。主要是用户方便，并不是强制性的。

The file that this is downloading is an index of all the available dependencies available in the Maven central repository for use in Maven-enabled projects, allowing them to be easily chosen and searched against within the Eclipse UI. It is mainly a user convenience, and isn't mandatory.
