I'm trying to jar some classes in a directory using the command:-

jar cvfmM Sketcher.jar Sketcher.mf -C *.class

My manifest file is as follows:-

Manifest-Version: 1.0
Main-Class: Sketcher
Created-By: Squills

When I try to jar the classes I get the error 'Constants.class\scaleSlider2.class : no such file or directory'

Any help would be most appreciated

Should probably be

jar cvfm Sketcher.jar Sketcher.mf  *.class

Commented:
Hi patelajk,

Its not able to find the class files.
after -C, you need to specify the directory name, where the .class files are present.

Cheers!

(assuming class files are in current directory)

I *think* you may need the "-" with Windows:

    jar -cvfm Sketcher.jar Sketcher.mf  *.class

My class files are in the current directory.

I tried:-

jar cvfm Sketcher.jar Sketcher.mf  *.class    (ie without the M flag)

This produced :-

java.io.IOException: invalid header field
        at java.util.jar.Attributes.read(Attributes.java:387)
        at java.util.jar.Manifest.read(Manifest.java:167)
        at java.util.jar.Manifest.<init>(Manifest.java:52)
        at sun.tools.jar.Main.run(Main.java:124)
        at sun.tools.jar.Main.main(Main.java:904)

The same happened with 'jar -cvfm Sketcher.jar Sketcher.mf  *.class'

I can get 'jar cvfmM Sketcher.jar Sketcher.mf  *.class' to produce a jar file now without errors but when I try to run the jar file it is corrupt or invalid.

I've saved my manifest file in Unicode format and left a blank line at the end of it.
