Today morning, one of my colleague was reported that, his
eclipse is not launching and It throws below error.
MESSAGE An error occurred
while automatically activating bundle
org.eclipse.core.resources
(26).
!STACK 0
org.osgi.framework.BundleException:
Exception in
org.eclipse.core.resources.ResourcesPlugin.start()
of bundle org.eclipse.core.resources.

(BundleContextImpl.java:1028)
I have verified all the plugins, and could not see any issue
with them. So where is the problem then?
I could solve the problem with Option (2).
Option 1: Try launching eclipse in clean
mode. This did not work in my case, it was throwing an error before it asks for workspace selection.
> eclipse -clean
Option 2: Delete .metadata/.plugins/org.eclipse.core.resources/.snap file workspace
directory.
Option 3: Most of the time option (2)
will work, if it's not working, try to delete all files from .metadata/ folder.
After launching your eclipse, you will not find your old
projects and workspace preference settings, you need to re-import into eclipse
workspace and need to configure eclipse preferences.
Why this would have
happened?
As per my understanding, this happens if you closed your
eclipse forcefully, shutdown the system forcefully before eclipse closes or
some files in workspace metadata would have been modified.
What is this .snap
files contain ?
*.snap files represent the changes in workspace state of the
IDE during the runtime. This is mostly for eclipse crash recovery plan. When a
crash happens these files are used to recover the state of eclipse workspace.
While Eclipse is running, information about what has changed
in the workspace is incrementally logged into various "snapshot"
files (including .snap). On normal Eclipse shutdown, the complete workspace state
is saved and the .snap files are deleted. When Eclipse crashes, the snapshot
files are used during the next startup to recover from the crash.
