如何将文件从一个eclipse项目导入另一个

Question

I know this question must have been asked before and i have gone through the solution but that didnt seem to solve my question. Suppose I have 2 projects in eclipse .ProjectA and ProjectB and ProjectA has file named FileA in package PackageA and ProjectB has a file named FileB in PackageB.Suppose i want to use a function of FileA in projectB.Is there any import statement which will allow me to do so.I dont want to copy paste the entire fileA in projectB.I just want something like

import ProjectA.packageA.fileA
class fileB
{
//calling function from fileA
int somethingsomething = fileA.somefunction();
}

I have done things like go to project right click and click on import and import the file.But i dont want the file to be present in my filelist of ProjectB.Please ,Can someone help me with this problem.Is this even possible?

Answer 1

First way

1. Right click on ProjectA and export as jar file.
2. Right click on ProjectB , Goto Build path -> Configure build path -> Libraries
3. Add external jar of ProjectA

Second Way,

1. Right click on ProjectB , Goto Build path -> Configure build path -> Projects
2. Click on Add, select ProjectA from list.

After this, you will be able to import classes in ProjectB which are defined in ProjectA by,

import packageA.fileA

Answer 2

Well your Project B needs the code of File A to execute it. You can either copy the file, or a .jar, or you copy the relevant code into the new project. You cannot just reference a piece of code but not add it to your Project in some way. When building your project to a .jar for example, this piece of information must be present and accessible for the program.
