Within Spring projects, almost all @Bean or @Component annotated Methods / Classe are listed as "without reference" which is totally ok due to the Spring architecture.
So, making things "private" or deleteing beans based on the UCD findings is not always recommended.

This is great! I am converting a rather large and old Spring 3 project to Spring Boot and there are a ton of unsed classes. This is going to help weed out the useless crap.
thanks for the plugin, but there's an issue that seriously limits its usability for me:
plugin checks also text files (or even more?) in the whole worksprace instead of limiting itself to the current project.
given Eclipse's long-standing an annoying failure to keep its idea of files' states up-to-date, I get a long list of
Resource is out of sync with the file system: ...
which is plain nonsense (files have not changed for a long time _and_ I've run refresh several times) and on top of it about files that have nothing to do with the project to be checked.
additionally, a check run takes unnecessarily long.
This is annoying for sure, but that's ultimately due to the defaults not being a good fit for your needs. I run into this myself, so I change them... but I REALLY wish the UCDetector settings supported import/export. That would make both my life and yours a lot easier!
After installing, my Eclipse Mars installation no longer identifies classes with compiler errors in Project Explorer view and no longer rebuilds automatically
After I install it, all I can see in Eclipse is a blank screen. Even uninstalling it does not restore the work space. I cannot even see my code. The only way to fix it is to go to Window, Reset Perspective. I have confirmed that this plug-in is the problem. I have uninstalled it and reinstalled it, and the same thing happens.
I cannot work without this tool anymore.
It helps you tidy up the code and removing methods/fields/classes that are never called anywhere.
It also suggests reducing methods/fields/classes visibility which is key to maintain the code.
Lastly it suggests fields that could be final. It sometimes takes a of work to get there, but you won't regret it.
Be careful when applying the changes if your code uses reflection.
I give it a 5/5 mark and wished it could do even more!
Thanks Jörg Spieler for this very useful tool!
This plugin helps you get rid of the dead code in your project. This means that your code-base will be reduced and the maintenance will be easier. Thanks to this plugin I removed 20.000 lines of code from a project of 130.000 without changing any behavior.
Anyway it is not perfect, and you'll find that you have more dead code than the one this plugin detects, but it will mark about 70-80% of it, so it is a great option.
I've found this very useful with the large code-base at my office. It does a great job of finding the dead code. Nice extras are that it will mark things as only used in unit tests and it finds when the access specifier is too general.
After a few hours trying out different solutions, you may end up having methods from your first tries forgotten throughout your code. UCDetector helps spotting them.

The update site works now: http://ucdetector.sourceforge.net/update/
It seems SourceForge has still trouble. See: https://twitter.com/sfnet_ops/
Invalid repository error!

I have created a bug for this on the Sourceforge tracker - suffice to say, it won't install.

I have to work on a Eclipse RCP project which contains full of copy-paste, dead code. This plugin helps me a lot during refactoring time.
