Config to make Eclipse Juno icons and tabs look small and nice in Linux

.gtkrc-eclipse

# Create a new file in your home directory called .gtkrc-eclipse

# call eclipse with this command:
# Gtk2 forced:
# export SWT_GTK3=0
# env GTK2_RC_FILES=/usr/share/themes/<YourTheme>/gtk-2.0/gtkrc:/home/<YourUser>/.gtkrc-eclipse '/path_to_eclipse/eclipse'

# In your Eclipse directory find the file 'e4_default_gtk.css'
# In this file there's a CSS class:

# .MPartStack {
#     font-size: 11;
#     swt-simple: false;
#     swt-mru-visible: false;
# }

# And you have two possible solutions:

# 1. Change font-size to something smaller
# 2. Just comment out or remove font-size from this class (works well for me)

Good work. Thanks a lot. Tested on Debian Jessie

Thanks!
You make my monkey developer day better.

Very nice! Worked on ubuntu 14.04

Truly appreciated..
I'm using the Eclipse Neon 4.6 (Ubuntu 16.04) and that script made my day 👍

Cool! Tried out on Eclipse Oxygen on Ubuntu Mate 16.10 beta2.
Thanks for the tip.

THX!!!
Linux Mint 18/Cinnamon with Eclipse neon.1

THX!!!

It works even on Oxygen GTK+ 2!
Just ignore the MPartStack bits (There aren't on .css file for Oxygen).
Thank you very much!!!

If you do wish to modify font-size under Eclipse Oxygen, this style has been refactored into e4_basestyle.css in this release.

Actually, for Oxygen we just need to force GTK 2 on Ubuntu 17.10.

Works for DBeaver (it is eclipse-based) on Debian Stretch
(css file can be found in /usr/share/dbeaver/plugins/org.eclipse.ui.themes_1.2.1.v20170809-1435/css/e4_default_gtk.css)
