The package collides with a type in java code

Question

I have a question about eclipse version 3.6.1.
I had run my code well before, but now I open the eclipse and my code appear red line at the package.
The error message is The package com.test collides with a type.
How should I solve this problem?
My code is as the following:

package com.test;

public class test extends Activity{
.....
.....
}

Thank you for your help~:)

Answer 1

I've changed the class name and the file name to Test, but it always wrong at the package com.test;, I have no idea about that problem.

At this point, Eclipse could just be confused.

Do a "project > clean" on all projects in your workspace. If that fails try the various other tricks that are typically used to de-confuse Eclipse.

Answer 2

Even after i corrected the naming conflicts and changed the package declaration to match its location, Eclipse showed this error message.

I deleted my project from the Eclipse package explorer(not from the computer) and then imported the same project after restarting the Eclipse. Problem solved!
