The Java Packager tool is a tool included in the JDK which allows to package Java applications from the command line. It is an alternative to using other packaging tools like Apache Ant.[1]
Note that the Java Packager does not automatically produce a Jar file. Many other formats are available, including native executable formats for the platform.
The Java Packager tool also manipulates modules (added in Java 9), allowing for example to package a module and all the modules it depends on.[2]
Example
[edit | edit source]For example, the following command will create a outputJar.jar file with the content of the classesDir directory, and will set the myPackager.MainClass as the executable class of the jar file:
javapackager -createjar -appclass myPackager.MainClass -srcdir classesDir -outdir out -outfile outputJar -v
