Every developer has a list of his or her useful Eclipse plugins. This is my list. This list is not meant to be complete and comprehensive. It is highly biased and opinionated list. There a lot of great plugins out there but this list falls under the “must have” for me personally.
If you are using Spring in your development, STS is a must have. Ctrl+Shift+L feature (for quick search) alone is a great reason to use STS in your daily work.
I found this plug-in to be great for quick access to a file outside of Eclipse. “This plug-in offers tight integration of system file manager (Windows Explorer, Gnome Nautilus, KDE Konqueror, Mac Finder, …) and shell (cmd.exe, Linux/Mac terminal) in Eclipse.”
