My project works great with Eclipse.
But when I tried to make it into a jar file or an executable file, it does not work.
I used the parameter "Export-Runnable JAR file"
The following message appears immediately after the eclipse of the export process is completed.
JAR export completed with jewelery, see details.
the details were ..
Exported with compilation warnings: Mario / src / Map.java
and the same for other classes such as
Exported using compilation warnings: Mario / src / Player.java
etc.
So I used another option "Export - JAR file"
It works fine and doesn't display anything when exporting from Eclipse.
But when I try to open the file, it gives me
Couldn't find the main class: Frame.Program will exit
