Make Composite Component Attributes from JARs Autocomplete

Question

I created a composite component and archived it in a * .jar file. My solution is based on this tutorial: How to pack a JSF2 composite component as a distributed JAR and this question: Java EE6> Packaging JSF facelets (xhtml) and ManagedBeans as a JAR . Everything works fine, but I cannot use autocomplete in Eclipse to add Composite Component attributes when I add it through a * .jar file. When I add it manually, i.e. Location code in resources/composite_components, everything works fine. I am using RAD 8.5.5 Thank you in advance.
