My Java application has got a package structure similar to this:

src/com/name/app 
src/com/name/app/do 
src/com/name/utils/db

How would I go about compiling Java files in these directories in to a runnable jar? I need to package required libraries into the generated JAR (jdbc).

I’ve always done these things in Eclipse but now I need to supply a couple of people with a way to compile the repository without the use of eclipse and I was thinking of making a makefile or a script that invokes the necessary javac pattern.

    First of all, consider using Ant for such a task.

    But since you asked for a manual process, you need to first create a manifest file, like so:

    Manifest-Version: 1.0
Created-By: 1.6.0 (Sun Microsystems Inc.)
Class-Path: lib/jdbc.jar lib/otherlib.jar
Main-Class: com.name.app.MainClass

    Replace the contents of Class-Path with your libs, and Main-Class with the fully qualified name of your main class.

    Then, you need to generate the actual .jar, using the following command:

    jar cfm app.jar MANIFEST.MF src/com/name/app/*.class src/com/name/app/do/*.class

    Where MANIFEST.MF is the previously mentioned manifest file, and the rest is the folders where your .java classes lie in.

    Finally, to run your app, you simply execute: java -jar app.jar.
