ablashov, I have to chime in with the others here and let you know that Eclipse does so many things for you, that in direct contradiction to what you assume, it is actually difficult to set up Emacs or Vi to do the same for you. One example is whole-workspace refactoring : Let's say you decide that a function (method) needs to take an extra parameter, a boolean, but actually, that is just to cover some corner cases, i.e., the argument will be false in most cases, but true for 5% of cases. But that method is used in 326 places. Guess what : changing method signature and refactoring ALL the code that uses that method is just a few actions in Eclipse. Eclipse --> Refactor --> Change method signature --> Add new parameter, boolean isCorner, default = false. You're done. It changes all 326 references to your method and rebuilds the project.

Truth be told, Eclipse is a key reason for Java's popularity. It makes working a pleasure and helps you focus on the actual work, not on the mechanics of how-to-get-it-done.
