how to extract jar from obr?

[Christopher Cody Welch]

For the purpose of automation, I would like to extract the .jar files from an .obr. How is this done?

[Sam Omidi · Accepted solution]

If you have myfile.obr for instance,

change the extension .obr to .zip as myfile.zip

and unzip it like any other compressed file.

An OBR is just a zip file.  Any zip extractor will be able to handle it, including command-line tools like unzip.
