I am developing an application in IntelliJ which has a class HackTrickBoard in a well defined namespace AbstractGames.ConcreteGames.mnkGame.HackTrick. In the same namespace I have created a new class HackTrickGUI with one method Main, in this method I simply instantiate a new HackTrickBoard class.
package AbstractGames.ConcreteGames.mnkGame.HackTrick; // Marked as unused in IntelliJ import AbstractGames.ConcreteGames.mnkGame.HackTrick.HackTrickBoard; public class HackTrickGUI { public static void main(String s[]) { //HackTrickBoard board = new HackTrickBoard(); AbstractGames.ConcreteGames.mnkGame.HackTrick.HackTrickBoard board = new AbstractGames.ConcreteGames.mnkGame.HackTrick.HackTrickBoard(); } } When I try to compile this code I am given an error
java: cannot find symbol symbol: class HackTrickBoard location: AbstractGames.ConcreteGames.mnkGame.HackTrick It seems that java cannot find the HackTrickBoard class yet knows where it is? IntelliJ had no issue finding it from the autocomplete menu and does not highlight its syntax as an error.
Is something wrong with Main?
In IntelliJ for the Run/Debug configurations I did not see an option for a command line application so I am starting this as a "Application", maybe this is the issue?

HackTrickBoardclass look like? Post its contents and the screenshot of the project view with this file.HackTrickBoard.package AbstractGames.ConcreteGames.mnkGame.HackTrick;. Hmm, how can I check if its excluded from compilation. I actually think that might the issue..x) on it, that is why I asked a screenshot of the project view, see this answer.
