I am currently developing a plugin, and the only real problem I get when compiling into a JARfile is that the config.yml or plugin.yml resource is out of sync with the file system. So I manually go and refresh those, although now I have to set to Refresh automatically (Eclipse). I get to a point where it starts telling me that the last exported JAR is out of sync. The only solution I have found so far is to either delete this old file, delete the release folder where it exports to, or to build it in a completely different folder than that. If anyone needs my filesystem structure, I can provide. Is there any explanation to this issue? Cheers, FlareLine.
