Often times, this error is causing by the mismatch order between “m” and “f” Jar options.
For example,
jar -cvfm manifest.txt example.jar com/mkyong/awt/*.class
The above command will causing the following error :
java.io.IOException: invalid header field at java.util.jar.Attributes.read(Attributes.java:406) at java.util.jar.Manifest.read(Manifest.java:199) at java.util.jar.Manifest.<init>(Manifest.java:69) at sun.tools.jar.Main.run(Main.java:150) at sun.tools.jar.Main.main(Main.java:1044)
Did you spot the error? The “m” and “manifest” is not match, the system is consider your manifest file as “example.jar”
The letters “m” and “f” must appear in the same order that “manifest” and “jarfile” appear.
The working command should be
jar -cvmf manifest.txt example.jar com/mkyong/awt/*.class
