Android R file not building when declare-styleable of type enum is added

Android R file not building when declare-styleable of type enum is added

Recently my Android workspace isn't compiling correctly anymore (the R
file isn't created). After trying the usual like cleaning i started
searching deeper. I discovered that when i comment out the items int my
attrs.xml file of the type declare-styleable with the format="enum" the R
file is build but not when they are present (not commented out). Is there
a recent change or something with the way you have the declare enums or
something? Here a piece of the project
working
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="SwipeListView">
<attr name="swipeOpenOnLongPress" format="boolean" />
<attr name="swipeAnimationTime" format="integer" />
<attr name="swipeOffsetLeft" format="dimension" />
<attr name="swipeOffsetRight" format="dimension" />
<attr name="swipeCloseAllItemsWhenMoveList" format="boolean" />
<attr name="swipeFrontView" format="reference" />
<attr name="swipeBackView" format="reference" />
<!-- <attr name="swipeMode" format="enum"> -->
<!-- <enum name="none" value="0" /> -->
<!-- <enum name="both" value="1" /> -->
<!-- <enum name="right" value="2" /> -->
