Tool, that automatically creates Java (wrapper) classes for any given Podio app. Any class includes corresponding from/to Item mappers. This can easily be used as a maven plugin.
See: https://github.com/daniel-sc/podio-java-codegen/wiki/Getting-started
Additionally, there is a simple interface for fetching/updating the wrapper classes. As extras there are proxies for automatic retry on Podio rate limit error/hit and a cache that circumvents unnecessary updates/writes.
