The first time you launch Eclipse, a dialog box pops up to let you workspace Launcher, which is the project storage path for Eclipse. However, when you tick "usethis as the default and does not ask again", the dialog box will not appear again at a later time when you start eclipse.
How to change the workspace path:
1 After you start Eclipse, select Window->preferences->general->startup and Shutdown->workspaces, tick "Prompt for Workspace on startup, and click OK. Launching eclipse again will show you a dialog box that lets you set the workspace path.
2 There is also a way to find the file "\configuration\.settings \org.eclipse.ui.ide.prefs" in the installation directory of Eclipse, after opening, modify the "Show_workspace_selection_ Dialog=false "is" show_workspace_selection_dialog=true ".
