MANIFEST.MF Class-path

[ben oliver]

I used eclipse and have a project. I saw in its MANIFEST.MF file it includes

Class-Path:

project_1.jar
project_2.jar

I believe this file is created by eclipse. However when I looked at the project's property --> Java build path, I only saw "project_1" there. So

Question 1: when I build this project, do I have to build (compile) "project_1" and "project_2" first ? Or do I just need to compile "project_1" first ?


Question 2: when I write ant script to create a jar file for this project, the jar will include a "META-INF" and a MANIFEST.MF inside. How do I specify in my ant script that I will just use this MANIFEST.MF ? (I assume I should provide this info in the "jar" target, but how ?)

Thank You.
