Question

我搞砸了我的Eclipse安装。我更改了工作区位置（File-＆gt; Switch Workspace）。现在它不会启动。我看到飞溅了几秒钟它关闭了。然后我尝试在命令行上使用-data参数同时使用旧工作区和新工作区，但行为相同。我也试过重启机器。

在 eclipse \ workspace.metadata.plugins \ org.eclipse.core.runtime.settings \ org.eclipse.ui.ide.prefs 中，我添加了SHOW_WORKSPACE_SELECTION_DIALOG的最后一行，但没有区别

EXIT_PROMPT_ON_CLOSE_LAST_WINDOW=false
IMPORT_FILES_AND_FOLDERS_RELATIVE=true
IMPORT_FILES_AND_FOLDERS_TYPE=23,1
PROBLEMS_FILTERS_MIGRATE=true
SWITCH_PERSPECTIVE_ON_PROJECT_CREATION=always
TASKS_FILTERS_MIGRATE=true
eclipse.preferences.version=1
platformState=1346849854920
quickStart=false
tipsAndTricks=true
SHOW_WORKSPACE_SELECTION_DIALOG=true

我如何取回它？

（编辑）我删除了.metadata目录，然后Eclipse重新启动。
