When I try to run the Island Demo on Unity 3 I get this error.

Assets/Editor/UpdateTreeColors.js(31,63): UCE0001: ';' expected. Insert a semicolon at the end.

this is the code when I doubleclick on the error in the log:

 @MenuItem("Terrain/Update Tree Lightmap Color")
 static function RebuildWithLightmap () {
     var tex : Texture2D = Selection.activeObject as Texture2D;
     if (tex)
     {
         if (Terrain.activeTerrain == null || Terrain.activeTerrain.terrainData == null)
         {
             EditorUtility.DisplayDialog("No active terrain in the scene", "No active terrain in the scene", "Ok");
             return;
         }
         
         Undo.RegisterUndo(Terrain.activeTerrain.terrainData, "Set Tree colors");
         UnityEditor.TerrainLightmapper.UpdateTreeLightmapColor(tex, Terrain.activeTerrain.terrainData);
     }
     else
         EditorUtility.DisplayDialog("Select a lightmap", "Select a lightmap", "Ok");
 }
 
 @MenuItem("Terrain/Update Tree Color")

     var tex : Texture2D = Selection.activeObject as Texture2D;
     if (tex)
     {
         if (Terrain.activeTerrain == null || Terrain.activeTerrain.terrainData == null)
         {
             EditorUtility.DisplayDialog("No active terrain in the scene", "No active terrain in the scene", "Ok");
             return;
         }
         
         Undo.RegisterUndo(Terrain.activeTerrain.terrainData, "Set Tree colors");
         UnityEditor.TerrainLightmapper.UpdateTreeColor//(tex, Terrain.activeTerrain.terrainData);
     }
     else
         EditorUtility.DisplayDialog("Select a lightmap", "Select a lightmap", "Ok");
