Hi everyone. I have a very serious problem and I need your help. I was solving an error in #Material for version compatibility and something happened to me when I opened the menu, I saw the console and it gave me an error in the part where the menu of my plugin was updated: SimplePing, And it turns out that the #PluginBase is not compatible with versions under 1.12 and is only compatible with high versions at 1.13 The console error is repeated because it is a repeating task Spoiler: ERROR IN CONSOLE Code (Text): [14:12:08] [Server thread/WARN]: [SimplePing] Task #32 for SimplePing v1.6.1 generated an exception java.lang.ClassCastException:

Hello, The error clearly explain.. the error: That mean, you can not do this ((PluginBase) invs), as the Inventory can not be casted to PluginBase. I'll just recommand to remove the cast.
That is because Inventory#getName() should not be used in 1.13, and do not even exists in 1.14. You have to check the Bukkit version, and adapt your code. Something like: Code (Java): String inventoryName; if (BukkitVersion >= 1.13) { inventoryName = p.getOpenInventory().getTitle(); } else { inventoryName = p.getOpenInventory().getTopInventory().getName(); } But this mean you'll have to use the spigot-api for 1.13 (to have both methods valid in your ide)
This should be compatible, yes; Theoretically, you should not be able to achieve what you want to do as Inventory metods are differents from 1.7 to 1.14. But i gave you a "glitch": by setting your spigot-api to 1.13 in your IDE, you'll can use the little code that I wrote, because both metods still exists in 1.13.
I think I gave him a solution Code (Text): private static String getInvName1_14(Player p) { if(Version.is1_13() || Version.is1_14()){ Inventory inv = p.getOpenInventory().getTopInventory(); String invName = inv.getTitle(); return invName; }else{ return null; } } And this I put in the if Code (Text): getInvName1_14(p)=="PING"
== checks for object equality, while equals() checks for determined equality(which was implemented in the String class so it's 100% safe) String comparison works differently; Your method's result instead of always being false, would actually always be undeterminable due to how the JVM handles Strings. If you wanna know why, read: https://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java
Comparing objects with == checks if they are pointing to the same memory location rather than the value (basically a reference comparison). Using #equals() allow you to compare the actual value. Code (Text): String str1 = new String("dank memes"); String str2 = new String("dank memes"); System.out.println(str1 == str2); If you try to run that code above, I'm pretty sure that prints out false (bear with the new String() for now).
I don't know exactly what you are doing but the error line tells you a lot about the actual problem Code (Text): org.bukkit.craftbukkit.v1_8_R3.inventory.CraftInventoryCrafting cannot be cast to org.bukkit.plugin.PluginBase This one tells you that you cant cast that object! Similar thing would look like this Code (Text): String test = "hello"; Integer i = (int) test Would not work as well because you cant cast String to int!
