I have recently discovered this new, must-have Eclipse plugin, which is very useful for those third-party libraries whose source-code you can’t easily find or link into your Eclipse: JDEclipse.
It doesn’t only decompile byte code into Java code, it does so extremely well, keeping line numbers at the correct place, such that you can actually debug through the decompiled source code and set breakpoints that actually work.
Disclaimer: Some users experienced this plugin to break their Eclipse Juno (see comments). Use at own risk!
Using keyboard shortcuts can vastly increase your productivity. Instead of switching between keyboard and mouse all the times, trying to figure out where that mouse cursor is, left/right clicking your way through context menus nested several levels deep, you could’ve just hit Alt–Shift-I, for instance, for inlining constants, variables, methods, etc… But how to remember the most important ones? Tricky…
This plugin will show a very annoying and obnoxious, big popup indicating the keyboard shortcut that you could’ve used just now instead of clicking through Eclipse menus with your mouse. For instance:
This will eventually annoy you so much that you’ll willingly use the suggested keyboard shortcut just to make the popup go away! And the best thing is, you’ll only learn the shortcuts for those actions that you really execute very often.
