Problem creating an jar file!

Question

Hello.
I am trying to create an executable jar file using the following command:
jar cmf MANIFEST.MF game.jar *.classHowever, I keep receiving the following error:
java.io.FileNotFoundException: MANIFEST.MF (The system cannot find the file spec
ified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:64)
        at sun.tools.jar.Main.run(Main.java:124)
        at sun.tools.jar.Main.main(Main.java:904)Why am I getting this error and how can I correct this?

Answer 1

Did you create a file called MANIFEST.MF? Is it in the same directory you are in now?
And by the way, according to what I see when I run the jar command, you need to specify the jar file first, and then the manifest file:Usage: jar {ctxu}[vfm0Mi] [jar-file] [manifest-file] [-C dir] files ...
Options:
    -c  create new archive
    -t  list table of contents for archive
    -x  extract named (or all) files from archive
    -u  update existing archive
    -v  generate verbose output on standard output
    -f  specify archive file name
    -m  include manifest information from specified manifest file
    -0  store only; use no ZIP compression
    -M  do not create a manifest file for the entries
    -i  generate index information for the specified jar files
    -C  change to the specified directory and include the following file
If any file is a directory then it is processed recursively.
The manifest file name and the archive file name needs to be specified
in the same order the 'm' and 'f' flags are specified.
Example 1: to archive two class files into an archive called classes.jar:
       jar cvf classes.jar Foo.class Bar.class
Example 2: use an existing manifest file 'mymanifest' and archive all the
           files in the foo/ directory into 'classes.jar':
       jar cvfm classes.jar mymanifest -C foo/ .
