How do you recompile a jar file?

Question

I took an old jar file and edited it. Now i have a folder that has all the files and I want to recompile them back to a jar file. How do i do this?

Answer 1

Jar files usually contain compiled java files (class-files) and resources. If you are allowed to make changes on this jar, you could disassemble the class files using JAD and after recompilation assemble them again with the command jar
