Eclipse Boot unresponsive, stuck in loading workbench state

Do the development of the students more or less will encounter eclipse boot to a certain extent, into the gray unresponsive state no longer move. The splash screen always stays in the loading workbench state. Repeated restarts, the state is still.

In most cases, it should be caused by an unhealthy file status error that shuts down the Eclipse workspace.

In the workspace directory, there is a. Metadata directory, which is the work area and the information of each plug-in, delete this directory, and then restart Eclipse, sure enough to start eclipse normally, but the original workspace configuration and project information also disappeared, the direct display is  Eclipse welcome interface.

So what can be done to ensure that the previous configuration is not lost?Then think of the status of the display when the start stop: "Loading Workbench", it seems to be related to this workbench plugin. View the. Metadata/.plugins directory in the workspace, in many folders

two were found: org.eclipse.ui.workbench and org.eclipse.ui.workbench.texteditor. Delete the two directories and restart Eclipse. Normal startup and the original project information is loaded correctly.

About Eclipse boot-up problems (the last time eclipse did not shut down properly, causing the startup to get stuck in the wrong way), its usual solution:

Scenario One (recommended use, if not this file, use scenario two):

To the <workspace>\.metadata\.plugins\org.eclipse.core.resources directory, delete the file. Snap

Scenario Two:

Enter the workspace/.metadata/.plugins/directory
Rename Org.eclipse.core.resources to Org.eclipse.core.resources_old.
Then restart Eclipse
Close Eclipse
Delete org.eclipse.core.resources
Rename Org.eclipse.core.resources_old back to Org.eclipse.core.resources
start Eclipse
