Eclipse - I want to access a class from the same package but under a different project, how?

Question

I use Eclipse IDE for my Java projects and all my projects(Project_1,Project_2 and so on) related classes are inside a package package_name.

I am currently working on 2 classes.

class_name.java(Project_2/package_name)

utility.java(Project_1/package_name)

All methods are public. How can I use the methods within utility.java in class_name.java ?

You can create a jar file from the source package and import it in the classpath of Project_2.

1- Right Click on desired package -> Export -> JAR File

2- Right Click on goal project -> build path -> Add external jar(or copy the jat file in lib folder of the second project and select the Add Jars in the Libraries tab of Java Build Path)

Why is it not immediately visible in `Project_2`? – Keir Simmons Mar 16 '14 at 13:02
Beacuase every projects have a independent build path that include necessary library(jar file) of the self project. – Hosein Masbough Mar 17 '14 at 04:42

If only one requires the other, you can use the Java Build Path property page of one project (Project 2) to have it require the other.
