This worked for me

On the Zipped folder of the ADT you initially downloaded unzip and navigate to:

adt-bundle-windows-x86_64-20140702\eclipse\plugins

Copy all the executable jar files and paste them on the

C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\eclipse\plugins

directory (or wherever your adt is located).
Any executable jar files missing in the plugin folder will be added. You should be able to launch eclipse

In my case  this error occurred because of windows 7 shortcuts  In windows we create shortcuts on desktop by using right click   send to   desktop  In my pc  there is no option for desktop  but there is one for  documents   I created the shortcuts there and then moved them to the desktop  Executing these shortcuts causes the error  Eclipse works fine when I run it directly from the folder where it is installed  I fixed it by using right click   create shortcut and then moving this shortcut to the desktop

In my case I have moved plugins folder mistakenly to another folder while taking backup of my unnecessary projects   Then while I was trying to run the eclipse exe I was getting the error-      The Eclipse executable launcher was unable to locate its  companion   shared library    I have simply copied the plugins folder to eclipse root directory  and it was working fine for me   If you have the folders backup in your computer then just copy and paste the folders on eclipse directory  you don t need to reinstall or change the ini file so far I realized

In my case eclipse ini entry for --launcher library was    --launcher library C  Users UserName  p2 pool plugins org eclipse equinox launcher win32 win32 x86 64 1 1 551 v20171108-1834  and on my machine  C  Users UserName  p2   folder was missing hence installed the eclipse again which created the  p2 folder structure at required location and now I am able to login successfully

The reason to that might be the 2 lines in eclipse ini  --launcher library C  Users UserName  p2 pool plugins org eclipse equinox launcher win32 win32 x86 64 1 1 400 v20160518-1444   for my case the reason was admin privilages so I had to move the folder from the path specified in ini to my eclipse plugins and change path in ini to    plugins org eclipse equinox launcher win32 win32 x86 64 1 1 400 v20160518-1444

I encountered the similar problem after installing new software  In my case  the problem was solved by   1  restoring  p2 subdirectory under my home directory  and  2  editing eclipse init file to have the updated java directory
