Eclipse-我想从相同的程序包访问一个类，但是在不同的项目下，该怎么办？

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 ?

Answer 1

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)

Answer 2

如果只有一个需要另一个，则可以使用一个项目（项目2）的Java Build Path属性页来让它要求另一个。
