macos - Eclipse hangs on loading workbench

Question

My eclipse stops loading workbench. I tried already starting with ./eclipse --clean

When starting from console it throws following exception:

java.lang.NullPointerException

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:

1. 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
   

2. Delete your .eclipse directory in your home directory. Launch eclipse. If that doesn't work,

3. Open eclipse under another user account. If it loads, you know the problem is with your account, not your eclipse installation.
