Solution

  • You can do :

    jar cfm jar-file manifest-addition input-file(s)
    • The c option indicates that you want to create a JAR file.
    • The m option indicates that you want to merge information from an existing file into the manifest file of the JAR file you're creating.
    • The f option indicates that you want the output to go to a file (the JAR file you're creating) rather than to standard output.
    • manifest-addition is the name (or path and name) of the existing text file whose contents you want to add to the contents of JAR file's manifest.
