Does anyone know how to configure IntelliJ Idea with Kotlin external annotations? If I use an external @Deprecated annotation the IDE picks it up correctly, but when I annotate it with @Nullable (from org.jetbrains.annotations.Nullable) the IDE just ignores it's nullability? Edit: It's for an external library, that's why I have to use the external annotations

is this external library written in Kotlin or written in Java?

It's written in Java (it's actually the Minecraft Spigot server) Example annotations:

<root>
    <item name='org.bukkit.inventory.PlayerInventory org.bukkit.inventory.ItemStack getItemInMainHand()'>
        <annotation name='org.jetbrains.annotations.Nullable'/>
        <annotation name='java.lang.Deprecated'/>
    </item>
</root>

the call route looks a little different here - it may be that using

.

directly on the result of

itemInMainHand

might be accidentally casting the object from

ItemStack!

to

ItemStack

rather than

ItemStack?

Oh I picked a bit of a wrong example, it also does this on none

.clone()

methods, for example: Also, the

.inventory

refers to an interface that only has methods, CTRL+Clicking the method confirms it refers to the externally annotated method

hmm that’s a good question

Yeah I indeed assumed the same, guess I'll indeed just try a :youtrack: issue

is there any chance that method is actually marked as deprecated by the library authors?

Nope, if I remove the

@Deprecated

from the external annotations it dissapears again

I see
