I have a .jar file called myfile.jar. Inside this jar file is a folder called images. Inside this folder called images, I have an image called hi.png. I want to update that image with a new version of that image, which is also called hi.png. I do not want to extract all of the files from the single jar file and then repackage them, I just want to update the image. So, I go to command line as usual, type a few lines of code, and then I do this command:
jar uf myfile.jar -C images hi.png
What I hoped to do with that command was to replace the old hi.png with the new hi.png. But, it gives me this error:
imageshi.png : no such file or directory
What do I do to fix this?
Extra info: I can not use something like WinRAR, I have to do this with command line.
-C is changing the local directory, and is looking for
hi.png there. It’s not controlling where you’re trying to inject it into the JAR file.
I would try making a new directory called
images, moving your local
hi.png into that, making
images a child directory of your current working directory, then just run this:
jar uf myfile.jar imageshi.png
