Upgraded from 14.04 LTS to 16.04 LTS but my Eclipse is not getting launched from the launcher on the side vertical bar. Giving me this error: The Eclipse executable launcher was unable to locate its companion shared library. enter image description here

Reinstalling is not fixing the issue.

Was referring to this thread but it seems there is not some easy way to get the launcher(the correct version of launcher) to get this issue fixed.

Moreover if i follow this link also why the same launcher is able to invoke eclipse when we do this from command line Vs ICON?

I am having Oracle JDK8 and using the installer to install Eclipse for Java EE Developers.

This is how my eclipse install directory looks like

root@ashu-700-430qe:/opt/eclipse/jee-mars/eclipse# ls -lrt
total 236
-rwxr-xr-x  1 root root 140566 Feb 12 16:55 icon.xpm
-rwxr-xr-x  1 root root  79058 Feb 12 16:55 eclipse
drwxr-xr-x  2 root root   4096 May 29 11:44 readme
drwxr-xr-x  2 root root   4096 May 29 11:44 dropins
-rw-r--r--  1 root root    798 May 29 11:44 eclipse.ini
drwxr-xr-x 11 root root   4096 May 29 12:37 configuration

This is how my eclipse.ini looks like for the launcher


and this is how the eclipse.desktop looks like

Please help.

  • This short way might be worked. Go to eclipse installed place then right click eclipse icon and select " Make link". Then drag and drop created Link icon where you want. Then double click it to launch. Thanks, Sandaruwan. – Sandaruwan Feb 6 '18 at 11:31

It's a permissions issue. You can either reinstall the package without sudo rights or change the permissions of /root/.p2 with

sudo chmod 775 -R /root/

I did the latter.

Also on CentOS the same issue, now in 2019. As splucena said above, changing permissions on the p2 folder --- under the extracted files --- to 775 and then running the install script did the trick, and I could run eclipse ok for all users.

As for the eclipse.desktop file, The entry below worked ok, with the application going into the 'Programming' category. Yes, Category=Development ends into programming, Category=Programming end in Other :)

As already suggested in the answer from splucena, you can edit the permissions of /root/.p2 That worked pretty well for me.

What I would simply add is that you don't necessarily need to add read and execute permissions to everyone in that folder for this to work.

You can just add those permissions to your specific user, by using ACL (access-control list):

# setfacl -R -m u:youruser:rx /root

To check ACL permissions were set properly:

# getfacl /root
