File hierarchy vs Package hierarchy in IDE(Eclipse)

Question

Let assume I have such class:

package com.stackoverflow.hierarchy;

class A {}

that is located in ~/MyProject/src/com/hierarchy

Is that possible to avoid compilation errors in IDE for A-class (like *The declared package "com.stackoverflow.hierarchy" does not match the expected package "com.hierarchy"*)

I've tried to search some answer in Java Build Path properties Project Properties. But I failed. Maybe some body can help with this staff?

Answer 1

It is the Java problem but not the eclipse problem.

From 7.2.1 Storing Packages in a File System in The Java Language Specification:

Under this simple organization of packages, an implementation of the Java platform would transform a package name into a pathname by concatenating the components of the package name, placing a file name separator (directory indicator) between adjacent components.

For example, if this simple organization were used on a UNIX system, where the file name separator is /, the package name:

jag.scrabble.board

would be transformed into the directory name:

jag/scrabble/board

and:

com.sun.sunsoft.DOE

would be transformed to the directory name:

com/sun/sunsoft/DOE

Your packages name should match the file pathname .So you should change Class A 's package from package com.stackoverflow.hierarchy to package com.hierarchy

or put the Class A into the folder /MyProject/src/com/stackoverflow/hierarchy
