How do I update a jar file after a list file and lib folder change?
I have hadoop-1.0.3 .jar. I made some changes to the lib folder (add external jar) and list files, and now I want to rebuild the jar file with the name hadoop-1.0.4.jar.
How can I do this?
Solution
In the shell, run:
jar cvfm hadoop-1.0.4.jar manifest.txt [list of files to package into a jar file].
You can run jar --help in the shell to check the different options available.
Basically, this particular command means:
-c: Creates a new jar file.
-v: Verbose output.
-f: Specifies the packaged file name.
-m: Contains the list file.
The rest should be easy to understand (output name, list file, list of files to package).
