scala how to get all classes based on ParentModule in the package and creating theirs instances

getPackageClasses

 def getModules(pack:String,args: AnyRef*)(ctor: Int = 0): Seq[ParentModule] = {
    var result = ListBuffer[ParentModule]()
    val cl = Thread.currentThread.getContextClassLoader
    val mirror = runtimeMirror(cl)
    val res = cl.getResource(pack.replace('.','/'))

    //HACK looking for files from package folder just for classloader
    for(f<-Directory(Path(res.getFile)).files){
      if (!f.name.contains("$anonfun$"))
        mirror.staticClass(pack +"."+ f.name.replace(".class",""))
    }


    val pkg = mirror.staticPackage(pack)
    for(t<-pkg.typeSignature.members) {
      if (t.isClass && t.info.baseType(typeOf[ParentModule].typeSymbol) == typeOf[ParentModule]){
         result+= mirror.reflectClass(t.asClass).reflectConstructor(t.info.members.filter(m =>m.isMethod && m.asMethod.isConstructor)
           .iterator.toSeq(ctor).asMethod)(args: _*).asInstanceOf[ParentModule]
      }
    }
    result
  }
