Spigot has decided to discontinue distribution of the Bukkit artifacts,
which means Bukkit "doesn't exist" after Minecraft 1.15. This commit
takes the plunge on that change and moves to the Spigot API rather than
the Bukkit API. Goodbye, Bukkit. Hello, Spigot.
The version is also bumped to 1.17 to give way to new features and bug
fixes otherwise blocked by staying on 1.13. Unfortunately, this brings
with it a swath of potential issues with version compatibility going
forward, because backwards compatibility in the API sometimes takes a
back seat, such as with the Material and EntityType enums. This commit
specifically changes some references that break compatibility with older
server versions, but compatibility with those is reinstated later.
Finally, the Spigot repository is changed to match the consensus about
which path on the Spigot Nexus instance to use. This seems to be what
everyone else is doing, so `bandwagon.jumpOn()`.
The integration only works reliably with the `clear-wave-` settings set
to `true`, because it relies on there being only one "current" wave.
This is a fundamental issue with the way sessions run right now, and is
another good example of why the Sessions Rework is necessary.
It is possible to achieve the exact same functionality by just making a
couple of Upgrade Waves before and after the waves that need to have
limited skill sets (thanks Lucy). With just a couple of quality-of-life
features like wave "triggers", it's possible to make things just the way
they were with the integration, but by using some more general building
blocks.
Closes#609
Jitpack is the recommended Vault repository now, and we've actually
already updated the comment for Jitpack to include Vault previously, so
let's just get rid of the HeroCraft repo now.
It's just UTF-8, Maven. No need to throw warnings all over the place...
This commit fixes some of the source encoding warnings Maven would print during compilation.
Metrics will greatly help the development process in terms of finding out which server versions people are running, as well as which features they are using. For now, we check to see how widespread Vault is, and how many arenas and classes people have.
Advanced bar charts are, at the time of this commit, not supported in the bStats dashboard. When they are supported again, we can look into usage statistics for specific settings and features.
This also swaps out the dependency on mockito-all with mockito-core, which is actually maintained. The purpose of updating is to allow for new Mockito features, such as mocking final methods, which happens due to the test resource org.mockito.plugins.MockMaker.
