eclipse shows an exclaimation mark beside my project and all the classes of that project shows no error messages. I cleaned the project and restarted again and the exclaimation mark still there.

problems tab output:

and i dont have any class named QRTest but i have QR01, therefore i renamed QR01 to QRTest
but the problem still there.

any ideas how to solve this problem?

Answer 1

This usually happens when one of the project dependencies is missing. Please check the Java Build Path to see if everything looks correct. You can also take a look to the “Problems” view.
