SVN checked-out folder does not show SVN status icon

The steps are as follows: TortoiseSVN settings--appearance and style (look and Feel)--icon overlay (image overlays) in the state cache (status cache) The default is changed to Shell (or other).

MyEclipse use SVN plug-in, originally normal, did not make any changes, suddenly one day, myeclipse to view the file, the file after the version number, the file's SVN icon status and so on are gone.
Check the plug-ins are in, update, submit and other operations can be used normally, but do not see the state.
Open: windows->preferences->general->appearance->labledecorations Check the SVN item.
At the same time, you can also open the WINDOWS->PREFERENCES->TEAM->SVN to do related settings.
=========================
Describe
Prints the status of the working copy files and directories. If there are no parameters, only locally modified items will be printed (no version library will be accessed), and the--show-updates option will add work revision and server expiration information. Using--verbose Prints the full revision information for each item.
The first six columns of output are a word wide, each column gives information about each aspect of the work copy project. The first column indicates whether an item is added, deleted, or otherwise modified.
''
Not modified.
A
The item that you are scheduled to add.
D
The item you are scheduled to delete.
M
The project has been modified.
R
The project has been replaced in the working copy. This means that the file is scheduled to be deleted, and then there is a file with the same name to replace it in the same location. This is some of the SVN icon status commands.
C
The content of the project (relative to the attribute) conflicts with the data that is being updated.
X
The project is related to an external definition.
' I '
Items are ignored (for example, using the Svn:ignore property).
'?'
The project is not under version control.
'!'
The item has been lost (for example, you moved with SVN or deleted it). This also shows that a directory is not complete (a check out or update interrupt).
'~'
An item is included in version control as an object (file, directory, or link), but has been replaced by another object. The second column tells the SVN icon state of the properties of a file or directory.
''
Not modified.
M
The properties of this item have been modified.
C
The properties of this project conflict with updates obtained from the version library. The third column appears only when the working copy is locked. (see "Sometimes you just need to clean up" section.) ）
''
The project is not locked.
L
The project is locked. The fourth column appears only for items that are scheduled to contain history additions.
''
No history is scheduled to be submitted.
'+'
Historical bookings are to be accompanied by submission. The fifth column appears only when the item jumps to the parent directory relative to it (see the "Use Branch" section).
''
The item is the child of its parent directory.
S
The project has been converted. The Sixth column displays the lock information.
''
When using--show-updates, the file is not locked. If you do not use--show-updates, this means that the file is locked in a working copy. This is some of the SVN icon status commands.
K
The file is locked in a working copy.
O
The file is locked by another user of the other working copy, and is only displayed when using--show-updates.
T
The file is locked in a working copy, but the lock is "stolen" and unavailable. The file is currently locked in a version library and is displayed only when using--show-updates.
B
The file is locked in a working copy, but the lock is "corrupted" and unavailable. The file is currently locked in a version library and is displayed only when using--show-updates. Expiration information appears in column seventh (appears only when you use the--show-updates option).
''
This item is up to date in the working copy.
' * ' In the server This project has a new revision. The remaining fields are wide and space-delimited, and if you use the--show-updates or--verbose option, the work revision is the next field. If the--verbose option is passed, the last submitted revision and the final author are shown later. The working copy path is always the last field, so it can include spaces. This section describes the solution to the problem of SVN icon status not appearing in MyEclipse.
