BukkitDev used to allow ZIP files to be uploaded to the plugin page, as seen in projects such as WorldEdit. As a result, I modularized my plugin into three JAR files and planned to upload them in a ZIP file. To my astonishment and utter dismay, the site rejected the file immediately because it is not a JAR file. Is there any workaround to this? Note: I did try changing the file extension from .ZIP to .JAR, with a warning to users that they'll have to change it back. What I was expecting was a message from the reviewer saying this was not allowed, and my plan was to respond with a request that the ZIP file be allowed. However, the reviewers simply approved the clearly defective file as-is.
