Note that the current version (1.0.8 ) works on windows only. I use those and I can compile the code between the Arduino IDE and eclipse without changes. Below are some simple instructions on how to keep your code Arduino IDE compatible. The current version works with cpp files only (no pde out of the box).
As you only need the Arduino IDE, Eclipe and the plugin this Arduino IDE alternative is completely free and open source. There is a free eclipse plugin available that makes development of big Arduino projects easier.
Latest version are tested and running on MAC
