MissingSerialVersionUID

Serializable classes should provide a serialVersionUID field.


    
//ClassOrInterfaceDeclaration
 [
  count(ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration
   /FieldDeclaration/VariableDeclarator/VariableDeclaratorId[@Image='serialVersionUID']) = 0
and
  count(ImplementsList
   [ClassOrInterfaceType/@Image='Serializable'
   or ClassOrInterfaceType/@Image='java.io.Serializable']) =1
and
   @Abstract = 'false'
]


Example(s):



public class Foo implements java.io.Serializable {
 String name;
 // Define serialization id to avoid serialization related bugs
 // i.e., public static final long serialVersionUID = 4328743;
}
