Budgetplex is all in one repository, Google-style.
Therefore, in theory, master is always stable enough to use in production.
However, that only applies after the first release (which is when I consider
this complete enough to be considered an actual set of plugins)
Simply go into each module's folder and execute the following:
gradlew jar
./gradlew jar
Want to modify Budgetplex for your own server? Go right ahead! Just make sure to follow the AGPL license. In other words, you must distribute your modified code somewhere on the Internet. A really easy way to do that is to just fork this GitHub repository and keep it public.
If you know of anyone violating the license, please open an issue on this GitHub repository!
