compile error: The import xxxx cannot be resolved

Question

I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual:

import ee.asus.kernel.House;

I got however the following error in compiling time:

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
The import ee cannot be resolved
House cannot be resolved to a type
House cannot be resolved to a type
House cannot be resolved to a type

at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10)
at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13)

It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

Answer 1

The error can't resolve the first part of the package name: ee. Are you sure the package starts with ee? I see your Window class package starts with main.ee, does your engine project start with the same package structure?

Answer 2

Look for the House class in your second project, opens it and see what package it is in.
(line "package xxx.yyy.zzz;" at the beginning of the House.java file)

Then make sure your Window.java file (class main.ee.asus.GUI.FrameWindow.Window) does have the line "include xxx.yyy.zzz.House;" in it.

Answer 3

I sometimes get weird behaviour with missing class files etc. when Eclipse is out of sync with the filesystem.

You could try refreshing all of your projects and doing a full rebuild.
