    Question How to make executable (.jar) file from a big project?

    I'm making a game in eclipse that uses only built in libraries like awt, swing, util, etc
    In this project I also use some images that I've already added their folder in the java build path
    Then I went to export -> java -> jar file and in the next window I've let it this way:



    But when I try to run the .jar file I got the following error:

    What is causing this error? how to make a final executable file from a big project containing many packages, etc?
    Thanks

    Moved to IDE section.

    Try opening the jar file in a zip utility to see if it has problems.

    That does NOT look like the contents of an executable jar file.

    I don't use an IDE to create my jar files so I can not help you. I use the jar command from a batch file.

    I went to export -> java -> jar file
    Try choosing "Export -> Java -> Executable Jar File"

    Tried too, didn't work, but got a different error: the program simply doesn't open. Doesn't show that error pop up that appeared before.

    To see the error message, open a command prompt window, change to the directory with the jar file and enter the command:
    java -jar THEJARFILENAMEHERE.jar
