I don’t know anything about SonarQube but any integration using Integration server can be done by specific or custom adapters or webservices or through a queue or may be with a file. That applies to every product. For example you don’t need to have SAP adapters to connect SAP to IS, instead you can import WSDL’s to integration server or manually call http client service within integration server. If SonarQube has Rest or Wsdl support you can use them or if it has some queue implementation somewhere you can just subscribe to those messages. Hope this helps.
