    Question How to compile a .jar from existing src in IntelliJ IDEA

    Hi everyone, great to meet you!

    I'm a complete beginner and I'm learning how to use IntelliJ, and still getting my head around concepts like packages, classes, etc.

    To begin with, one of the things I'd like to try is taking an existing src with working code (used with permission from the developer), and try to compile it to a .jar file, without changing anything, just to see if the compilation process works.

    I'm having great difficulty figuring out exactly how to do this. I have the project open in IntelliJ, with the src folder within the project files on the left. I know that I need to open [something] in a Terminal window, and type "javac [something].java", the problem is that I don't know what the [somethings] are supposed to be.

    Can any offer a simple, easy-to-follow, step-by-step solution to this? I'll be extremely grateful if you can, since so far all the Googling in the world has led me to setting up an account here in order to ask you guys 😊

    Please be prepared for me to not understand at least one of the steps, and need clarification on it.

    Thanks in advance!

    Default Re: How to compile a .jar from existing src in IntelliJ IDEA

    Moved to IDE section.

    Using basic java tools, a jar file is built by
    first compiling(using javac) the source(files ending with .java) which creates .class files
    then creating a manifest file with the program's starting class(has main method)
    and then using the jar command to put all the parts into the jar file.

    I assume most IDEs do all that.
    If you don't understand my answer, don't ignore it, ask a question.
