Eclipse " save as ANT script" or not?

[ytrewqc]

I use eclipse and when i export a project I go to: file>export>java>runnable jar file
and in there, there is an option to "save as ANT script"
(Then i make a text file and type "java -jar name.jar")
What is this ANT script option because it doesnt matter if you choose it or not, the program still works fine.(all it does is create an extra file)

So should I save it as an ANT script, or as an regular jar file?


*also another question, is there any way to export the project without having to use the text document: "java -jar name.jar"? So you can just run the jar file directly by clicking it?

run the jar file directly by clicking it?

The JRE installation can make entries with OS to do that.
