inconsistent notation for importing inner classes

[305pence]

Basically, i'm having trouble with importing org.bukkit.entity.EnderDragon.Phase

i tried this code to summon an ender dragon and set it's phase so it doesn't just float there

IMPORT org.bukkit.entity.EntityType
IMPORT java.lang.Math
IMPORT org.bukkit.entity.EnderDragon.Phase
FOR player = getPlayers()
 world = $world
ENDFOR
pu = {"location.shrine"} 
locS = pu.clone()
pu = {"location.mobspawn"} 
locM = pu.clone()
x = locM.getX() - locS.getX()
z = locM.getZ() - locS.getZ()
rAngle = Math.atan(x/z)
IF z < 0
 angle = Math.toRadians(180) + rAngle
ELSE
 angle = rAngle
ENDIF
loc = locS.add(64*Math.sin(angle), 15, 64*Math.cos(angle))
dragon = world.spawnEntity(loc, EntityType.ENDER_DRAGON)
dragon.setPhase(EnderDragon.Phase.CHARGE_PLAYER)

and i got the error below

@305pence Hello,

The problem seems to be related to the inner class.

Java denote the inner class with $ sign instead of .(dot), so all you have to do is

IMPORT org.bukkit.entity.EnderDragon$Phase

Let us know if it doesn't work.

[gerzytet]

@wysohn In that case, would the class be called Phase or EnderDragon$Phase in your code?

[wysohn]

@gerzytet I believe it is just Phase

[305pence]

yeah, that seems to work

[gerzytet]

I'm reopening this as a low priority bug because requiring this internal notation for importing is inconsistent with java and the javadocs.

[gerzytet]

I'm especially suprised that no-one who uses sponge has complained yet. Sponge has inner classes everywhere
