Make jar file from folder

Question

i have a folder on my desktop named theme.I am new to Linux totally. So what do I do to create a jar file from this folder? I found this example but It doesn't work for me.

jar -cvf theme.jar

Answer 1

Jar files are really just zip files, renamed to .jar . Just use any folder zipping tool (such as the zip command).

zip -r theme.jar /path/to/desktop/theme

Answer 2

You are failing to specify the input files for the jar.

Navigate to the theme/ directory using the cd command in Terminal. If you want to include everything in this directory in your jar file, use the following command.

jar cvf theme *

Note that the * character (wildcard) indicates you want to include all files and subdirectories.
