Eclipse hangs on loading workbench

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

When starting from console it throws following exception:

java.lang.NullPointerException

The procedure shown at http://off-topic.biz/en/eclipse-hangs-at-startup-showing-only-the-splash-screen/ worked for me:

  1. cd .metadata/.plugins
  2. mv org.eclipse.core.resources org.eclipse.core.resources.bak
  3. Start eclipse. (It should show an error message or an empty workspace because no project is found.)
  4. Close all open editors tabs.
  5. Exit eclipse.
  6. rm -rf org.eclipse.core.resources (Delete the newly created directory.)
  7. mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)
  8. Start eclipse and start working. :-)

In other answers:

eclipse -clean -clearPersistedState

is mentioned - which seems to have the same or even better effect.

Here is a script for MacOS (using Macports) and Linux (tested on Ubuntu with Eclipse Equinox) to do the start with an an optional kill of the running eclipse. You might want to adapt the script to your needs. If you add new platforms please edit the script right in this answer.

#!/bin/bash
# WF 2014-03-14
#
# ceclipse:
#   start Eclipse cleanly
#
#   this script calls eclipse with -clean and -clearPersistedState
#   if an instance of eclipse is already running the user is asked
#   if it should be killed first and if answered yes the process will be killed
#
# usage: ceclipse
#

#
# error
#
#   show an error message and exit
#
#   params:
#     1: l_msg - the message to display
error() {
  local l_msg="$1"
  echo "error: $l_msg" 1>&2
  exit 1 
}

#
# autoinstall
#
#  check that l_prog is available by calling which
#  if not available install from given package depending on Operating system
#
#  params: 
#    1: l_prog: The program that shall be checked
#    2: l_linuxpackage: The apt-package to install from
#    3: l_mac
