Avoiding resource is out of sync with the filesystem

Question

I develop Java code with Eclipse and regularly get this message      resource is out of sync with the filesystem    Right-click   Refresh will always clear this    But why can t Eclipse refresh automatically when it finds this condition  Are there cases where you want the resource to be out of sync    If there are such conditions and they don t apply to my work  is there a way of getting Eclipse to refresh automatically when it encounters this state    I appreciate that it should refresh as little as it needs to in normal development to increase performance for human developers    UPDATE  2012-06-25   My latest update  Version  Indigo Release Build id  20110615-0604  no longer shows  Preferences - General - Workspace - Refresh Automatically There is an option  Refresh on access  - should I use this

Just right click on the file or on the project and click Refresh  The error will vanish  I also faced the same issue and it worked for me

I was not able to resolve this error by either refresh or by turning on  native polling  workspace feature  Turned out my project was also opened in two instances of eclipse  Once I closed the other instance  the error went away  So make sure your project is only opened at one place if you are seeing this error

If this occurs trying to delete a folder  on  nix  and Refresh does not help  open a terminal and look for a symlink below the folder you are trying to delete and remove this manually   This solved my issues

This happens to me all the time   Go to the error log  find the exception  and open a few levels until you can see something more like a root cause  Does it says  Resource is out of sync with the file system     When renaming packages  of course  Eclipse has to move files around in the file system  Apparently what happens is that it later discovers that something it thinks it needs to clean up has been renamed  can t find it  throws an exception   There are a couple of things you might try  First  go to Window  Preferences  Workspace  and enable  Refresh Automatically   In theory this should fix the problem  but for me  it didn t   Second  if you are doing a large refactoring with subpackages  do the subpackages one at a time  from the bottom up  and explicitly refresh with the file system after each subpackage is renamed   Third  just ignore the error  when the error dialog comes up  click Abort to preserve the partial change  instead of rolling it back  Try it again  and again  and you may find you can get through the entire operation using multiple retries

When you open an Eclipse workspace from within a clearcase view and try to rename the project  you will often get the pop-up warning        Resource    project    is out of sync with the file system     If refreshing the project does not fix the problem  then do the following workaround  a  Open workspace WITHOUT being in a view b  Select the project in Project Explorer c  ClearCase -  Associate Project  project should now look like project      d  Right click project -  Refresh  vob sub-folders should now be empty  e  Right click project -  Rename     f  Enter New name  Now you can close the workspace  reopen it in a view and refresh the project  You may also dissociate the project if you prefer the project not to be associated with the vob

You can enable this in Window - Preferences - General - Workspace - Refresh Automatically  called Refresh using native hooks or polling in newer builds     The only reason I can think why this isn t enabled by default is performance related   For example  refreshing source folders automatically might trigger a build of the workspace  Perhaps some people want more control over this   There is also an article on the Eclipse site regarding auto refresh   Basically  there is no external trigger that notifies Eclipse of files changed outside the workspace  Rather a background thread is used by Eclipse to monitor file changes that can possibly lead to performance issues with large workspaces

For the new Indigo version  the Preferences change to  Refresh on access   and with a detail explanation   Automatically refresh external workspace changes on access via the workspace   As    resource is out of sync with the filesystem    this problem happens when I use external workspace  so after I select this option  problem solved

If you are a regular Eclipse user than you might have got this error many times  The error simply says     you   ve made changes in files in your workspace from outside eclipse     The simplest solution would be to select the project and press F5  Right click -  Refresh    if you need more explanation you can read from this web site

A little hint  The message often appears during rename operation  The quick workaround for me is pressing Ctrl-Y  redo shortcut  after message confirmation  It works only if the renaming affects a single file
