Creating a JAR File
The basic format of the command for creating a JAR file is:
jar cf new-jar-file files-to-be-converted-to-jar
The options and arguments used in this command are:
The c - to create JAR file.
The f - output to go to a file rather than to stdout.
new-jar-file - name of the resulting JAR file. By convention, JAR filenames are given a .jar extension, though this is not required.
files-to-be-converted-to-jar argument - list of files to be converted to jar .Use space to seperate each file.
If any of the input-files are directories, the contents of those directories are added to the JAR archive recursively.
Above command will generate a jar in current directory.
This command will also generate a default manifest file for the JAR archive.
You will need to use the java command to run a .jar file:
java -jar MyApplication.jar
If you don't have java installed, you can fix that by installing the default-jre package from oracle website.
You can see if you already have java installed by running in a terminal or in command line:
java --version
