To migrate launch configs between different workspaces simply copy the .launch files from:
/eclipse-workspace/.metadata/.plugins/org.eclipse.debug.core/.launches
To exclude annoying packages or classes when doing automatic organisation of imports with Ctrl+Shift+O create a a “Type Filter” under Windows → Preferences → Java → Appearance → Type Filters
.
My current list:
scala.* java.awt.* junit.* org.joda.*
As of 2018 the subversive project seems to be dead, so we must use subclipse. Install it from the Eclipse Marketplace and then:
sudo apt install libsvnclientadapter-java
Specify the folder where libsvnjavahl-1.so
is located as library path in eclipse.ini
(the line must come directly after -vmargs
)
-vmargs -Djava.library.path=/usr/lib/x86_64-linux-gnu/jni

Start with:
GTK_OVERLAY_SCROLLING=0
This will permanently reserve place for the scroll bars and no content will be hidden.
Using Kubuntu 20.04 I don't like the miniscule scroll bars that slightly widen when hovering over them. Setting a min size works as follows:
Edit .config/gtk-3.0/gtk.css and add these lines:
.scrollbar.vertical slider, scrollbar.vertical slider { min-width: 7px; } .scrollbar.horizontal slider, scrollbar.horizontal slider { min-height: 7px; }
This happens sometimes when upgrading a workspace to a new version of Eclipse (most recently to me when upgrading vom 2018.09 to 2018.12).
Window→Preferences→Java→Editor→Content Assist→Advanced
Now make sure the following are all ticked in the top and bottom sections:
Apply the changes and then close and re-open your project and it will build the autocompletions which will then become available when you hit Ctrl-Space.
