Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: Class[cc]

I'm looking for a solution for the Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: Class

Say
I have 2 completely independ puppet modules (a & b) that depends on puppet module cc
class a {
class {'::cc':}
.....
}

class b {
class {'::cc':}
.........
}

Is there a way to resolve this problem.
