The GitHub sharing of long files is broken in IDEA 2019.3

[lukbukkit]

If you want to share long files via GitHub in IDEA 2019.3, you can't, because the package name of a data class changed.

Thanks to #8 @iasemenov, who notified me about this issue and created a pull request.

The problem is fixed for the upcoming relase, but the plugin currently only works in this version. The plan is to create two Gradle builds of the plugin (one pre 2019.3 and the other post 2019.3) and distrubute these two version. If the plan works, theere will also a version of the plugin for older IDE versions.
