Hey. Today I have a need to fix whois for myself by removing the player’s coordinates from there. To do this, I downloaded the sources, installed BuildTools according to the instructions, and for the sake of interest I made the test compilation of the plugin unchanged. As a result, I received an error:
[ERROR] D: \ BuildTools \ apache-maven-3.6.0 \ bin \ Essentials \ src \ com \ earth2me \ essenti
als \ OfflinePlayer.java: [39,7] error: OfflinePlayer is not abstract and does not
override abstract method setRotation (float, float) in Entity
Since I use maven for the first time - most likely the problem is in me. Help me solve it, please. Thank.
OS: Win 7 x32, Java (JRE & JDK 1.8.0_201)

This is quite common - often Spigot updates and causes the build process to break. I'll update the source soon.

For now, if you're using an IDE like IntelliJ IDEA or Eclipse, you should be able to generate the missing methods by opening EssentialsX's OfflinePlayer class and implementing the missing methods.

Thanks a lot, now I can forbid players to watch the coordinates of other players in whois!

This has been fixed by 3d97e93 - you can download the latest source and it should now compile without error.
