[jole431f]

• CodeClimateReportPlugin.java:
  - ObjectMapper.setSerializationInclusion() is deprecated due to new jackson version
  -> replace with: private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper().setDefaultPropertyInclusion(NON_NULL);
  -> add .writerWithDefaultPrettyPrinter() to ObjectMapper Call

   - getLocation(): path attribute for codeclimate report should be set after checking whether sourceLocation is an instance of FileLocation
