+ | ===== Configuration ===== | ||
+ | |||
+ | ==== Migrate launch configurations ===== | ||
+ | |||
+ | To migrate launch configs between different workspaces simply copy the .launch files from: | ||
+ | |||
+ | <code> | ||
+ | /eclipse-workspace/.metadata/.plugins/org.eclipse.debug.core/.launches | ||
+ | </code> | ||
+ | |||
+ | ==== Organise Imports ==== | ||
+ | |||
+ | * Automatically organise imports: Ctrl+Shift+O | ||
+ | * Static import: Ctrl+Shift+M | ||
+ | |||
+ | 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: | ||
+ | <code> | ||
+ | scala.* | ||
+ | java.awt.* | ||
+ | junit.* | ||
+ | org.joda.* | ||
+ | </code> | ||
+ | |||
+ | ===== SVN support ===== | ||
+ | |||
+ | As of 2018 the subversive project seems to be dead, so we must use subclipse. Install it from the Eclipse Marketplace and then: | ||
+ | |||
+ | <code bash> | ||
+ | sudo apt install libsvnclientadapter-java | ||
+ | </code> | ||
+ | |||
+ | Specify the folder where ''libsvnjavahl-1.so'' is located as library path in ''eclipse.ini'' (the line must come directly after ''-vmargs'') | ||
+ | |||
+ | <code> | ||
+ | -vmargs | ||
+ | -Djava.library.path=/usr/lib/x86_64-linux-gnu/jni | ||
+ | </code> | ||
+ | |||
+ | see also https://github.com/subclipse/subclipse/wiki/JavaHL-on-Linux | ||
+ | |||
+ | ===== Troubleshooting ===== | ||
+ | |||
+ | see [[kubuntu|KDE 5 / Kubuntu Tipps & Tricks]] | ||
+ | |||
+ | ==== Scroll bars hide content ==== | ||
+ | |||
+ | Start with: | ||
+ | <code bash> | ||
+ | GTK_OVERLAY_SCROLLING=0 | ||
+ | </code> | ||
+ | |||
+ | This will permanently reserve place for the scroll bars and no content will be hidden. | ||
+ | |||
+ | See https://bugs.eclipse.org/bugs/show_bug.cgi?id=519728 | ||
+ | |||
+ | ==== Scroll bars too small ==== | ||
+ | |||
+ | 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: | ||
+ | |||
+ | <code> | ||
+ | .scrollbar.vertical slider, scrollbar.vertical slider { | ||
+ | min-width: 7px; | ||
+ | } | ||
+ | .scrollbar.horizontal slider, scrollbar.horizontal slider { | ||
+ | min-height: 7px; | ||
+ | } | ||
+ | </code> | ||
+ | |||
+ | ==== Autocompletion not working properly ===== | ||
+ | |||
+ | 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: | ||
+ | |||
+ | * Java Non-Type Proposals | ||
+ | * Java Proposals | ||
+ | * Java Type Proposals | ||
+ | |||
+ | 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. | ||
