Eclipse freezing at startup - before loading workspace very good answer on this post. repeating the answer that worked for me

In your workspace directory perform the following steps:

cd .metadata/.plugins

mv org.eclipse.core.resources org.eclipse.core.resources.bak

Start eclipse. (It should show an error message or an empty workspace because no project is found.)

Close all open editors tabs.

Exit eclipse.

rm -rf org.eclipse.core.resources (Delete the newly created directory.)

mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)

Start eclipse and start working. :-)

Get a backup copy of the  metadata  plugin org eclipse core resources folder  then delete that folder and launch eclipse  That should launch the workspace  but all projects will be gone as org eclipse core resources keeps a list of all projects   Next  close eclipse properly and copy back org eclipse core resources from back up to  metadata  plugins  folder overriding the existing one   Open eclipse and things should work fine with all your projects back to normal

There are many possible reasons for this sort of behaviour  In addition to running from a shell prompt as you have  it s worth looking for clues in your workspace log file  which is the file  metadata  log under your workspace directory   the NPE that s coming up for you looks like it could have to do with the logging code itself  but the log may still help determine what was going on before the error   Web searches for messages you find often yield suggestions for deleting various directories or files and starting again  I ve sometimes been able to just remove parts of  metadata  plugins org eclipse ui workbench workbench xml  though  for less destructive solutions

None of the solution helped me for my case   I found the working solution though  I read that this happens when ADT plugin is not updated properly in Eclipse   Solution From Eclipse      1  Go to Help Tap 2  Click Check for Updates   Update everything and whoa  No longer freezing at starting Eclipse

The best solution I found is to delete this file  workspace  metadata  plugins org eclipse e4 workbench workbench

After some investigation about file dates I solved the same issue  which is a randomly recurrent trouble on my Kepler  by simply deleting the following file in my local workspace   metadata plugins org eclipse jdt core variablesAndContainers dat  with negligible impact on the workspace restoring   I hope it can help  someone else

In your workspace you will find hidden folder name  metadata in which you will find another hidden folder   mylyn  delete it and empty your trash go to task manager stop the process of Eclipse and start again Eclipse this time it will work   Enjoy

User · Answer

no need to delete the entire metadata  just try deleting the  snap file under org eclipse core resources in your workspace folder ex       workspaceFolder metadata plugins org eclipse core resources

It might also help to try to load and save the workspace with a newer eclipse version   I am using eclipse 3 8  When starting up the splash screen would hang  There were no error messages in the log  What helped was to open the workspace with eclipse 4 2 2  After opening and closing the workspace I was able to load it again with 3 8

DISCLAIMER  THIS WILL DELETE ALL OF YOUR ECLIPSE WORKSPACE SETTINGS AND YOU WILL HAVE TO RE-IMPORT ALL YOUR PROJECTS  THERE ARE LESS DESTRUCTIVE ANSWERS HERE  Try the following    Delete the  metadata folder in your local workspace  this is what worked for me   It seems that it contains a  LOCK file that if not properly closed  prevents eclipse from starting properly  On Unix based systems you can type following on command line   rm -r workspace  metadata  Delete your  eclipse directory in your home directory  Launch eclipse  If that doesn t work  Open eclipse under another user account  If it loads  you know the problem is with your account  not your eclipse installation

The trouble with deleting files in  metadata directory is that you would have to start your workbench from scratch  So  it might take awhile to restore all your projects  especially if you have a number of them   Restoring  metadata from a backup just by replacing the existing files with the old backed up ones worked for me

Pretty old question but the most simple answer isn t yet posted  Here it is   1  In  workspace   metadata  plugins org eclipse e4 workbench delete workbench xmi file   In most cases it s enough - try to load Eclipse  Still you have to re-configure your specific perspective settings  if any  2  Now getting problems with building projects that worked perfectly  As of my experience following steps help  - uncheck Projects- Build automatically - switch to Java perspective  if not yet   Window -  Open perspective -  Java - locate Problems view or open it  Window -  Show view -  Problems - right-click on problem groups and select Delete  Be sure to delete Lint errors - clean the workspace  Project -  Clean    with option Clean all projects - check Projects- Build automatically  - if problems persist for some projects  right-click project  select Properties -  Android and make sure appropriate Project Build Target is chosen 3  It was always sufficient for me  But if you still get problems - try  george post recommendations

Here s a less destructive method that worked for me   I m on Windows machine with a copy of Spring Tool Suite  an extension of Eclipse  which I m running from a random directory  In my command line prompt  I had to navigate to the directory which contained my STS exe and run  STS exe -refresh    After that  I could open my Eclipse the normal way  which was through a pinned taskbar icon

You have to delete org eclipse e4 workbench folder inside metadata plugins  which you can find in your workspace folder  Deleting this folder solved the problem for me  hope it helps someone else
