Launch4J - main jar, all dependencies into one exe

How do I include all the jars into Launch4J so that I can build an exe without any dependencies?

Thanks.

Solution

  • I think the trick here is to package all of your class files and all dependencies within a single jar. This means extracting the contents of those dependent jars, and then repackaging them.

    I think an entirely manual process is also possible. Compile your class file into a build directory. Open each dependency (jar file) as if it were a plain ZIP, and extract the contents into the directory with your class files. Repeat this for every jar. Now your code and the dependencies sit side by side - package the entire set of files into a single JAR and proceed with the steps needed to package that up with Launch4J.
