Updating a JAR file

Updating a JAR file

At times, requirement to update an already delivered JAR file will need to be handled. Of course, JAR file is a way of packaging and delivering Java class file and related metadata files in a package. But having an easier way is always welcome by the developer group.

The following command when executed on a command line will achieve updating a JAR file with 1 or more files as needed

jar uf jar-file input-file-name(s)

uf          :    indicates update and file
jar-file    :   the jar file that needs to be updated
input-file-name(s)   :   the name of file(s) that needs to be updated in the jar file.
