1. Quick fix for "There is no class/annotation with the specified name [JSR-299 §5.1.1]" problem marker

In case when Bean class or Stereotype does not exists there should be a quick fix:
"Create Bean Class/Stereotype". This quick fix should run Creation wizard for Bean Class or Stereotype with selected "Add @Alternative" option

2. Quick fix for "<class> element must specify the name of an alternative bean class [JSR-299 §5.1.1]" and "<stereotype> element must specify the name of an @Alternative stereotype annotation [JSR-299 §5.1.1]" problem markers

In case of existing of Bean Class or Stereotype and when Bean Class or Stereotype has no @Alternative annotation there should be a quick fix:
"Add @Alternative annotation to Bean Class/Stereotype"

3. Quick fix for "There is no class with the specified name [JSR-299 §9.4]/[JSR-299 §8.2]" problem markers

In case when Decorator or Interceptor does not exists there should be a quick fix:

"Create Interceptor/Decorator". This quick fix should run Creation wizard for Interceptor or Decorator

1. Create CDI Project
2. Create beans.xml file and open it in JBoss Tools XML Editor
