A Few Compiler Arguments Make All The Difference In The World!

I often find that Eclipse is as much a burden as a joy to work with, but there are some small/simple changes I made to Eclipse I made in the past that made all the difference in the world to my development environment.

The first is in the shortcut path to startup Eclipse (windows). By adding the following string after your “C:your-path” you will set a memory limit size and a clean to Eclipse each time it starts up. This has kept my Eclipse from crashing when it used to crash about 3 times a day previously.

-clean -vmargs -Xms512M -Xmx512M -XX:MaxPermSize=512M

Eclipse Shortcut Properties

The second change is to the Flex Compiler itself. Select your project and go to Project > Properties > Flex Compiler. In your additional arguments text input add this to your other arguments.

-incremental=true -keep=true

Flex Properties / Flex Compiler Options

This makes sure that the compiler works incrementally and the compiled source code is kept. Do you need to keep the compiled source code? No, but I like to.

Hope that helps improve your Flex/Eclipse workflow!
