This is a general step that happens when m2e/m2eclipse (Maven integration for Eclipse) is installed, whether projects are actively using it or not.
這是因為m2eclipse(maven插件)要在啟動時需要進行的一個步驟。
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.
我們可以停止這個動作。方法:Windows -> Preferences -> Maven 取消勾選 Download repository index updates on startup
