eclipse question

hey guys. i have just went back to college recently and started studying some java again. i tried to run some of my code from last year in college but something i never seen before came up; "select what to run: ant build, ant build..". i tired clicking both ant builds both nothing came up in the console.. can someone explain to me why my code isn't running and what this ant build option is about?

normally when i pressed Run my code ran straight away in console now thing ant build stuff comes up and it won't run

thanks!

If you don't know what ant is, see the following link:
Apache Ant
Its an extremely handy utility for complex build projects (things that require singing, lots of dependent libraries, file copying, jar packaging, etc...). For simple projects, it shouldn't be necessary, and it seems that your Eclipse configuration is set to run things as ant. I can't give specific advice, but I'd say make sure your main class is selected when you try to run, and/or go to Run->Run As or Run Configurations to try and see if there is a setting there.

thanks mate
