I have installed eclipse in Ubuntu 18.04 via Snap. And in the snap folder, I can see eclipse, where I want to add few lines in eclipse.ini file, but I'm getting "E45: 'readonly' option is set (add ! to override) " msg , even I'm not able to change file permission.
-rw-rw-r-- 1 root root 586 Apr 5 20:25 /snap/eclipse/12/eclipse.ini
/snap/eclipse/*/eclipse.iniis impossible, but I've found a way to use a differenteclipse.iniwhen launching Eclipse. – brandizzi Jul 03 '18 at 20:32
