java.lang.VerifyError while retrieving associated entities. (Happens only when this is run as part of a maven execution) - sap-cloud-sdk

Question

We have code looking like this.
HeaderCDSForPRForGuidedBuying requisitionHeader = readHeaderInternal(draftUUID);
try {
requisitionHeaderAddress = requisitionHeader.getGuidedProcmtReqnDelivAddrOrFetch();
} catch (NullPointerException ex) {
logger.error("Exception occurred: No Address is associated with the requisition header", ex);
}
As can be seen, we are first fetching one entity(header), and then associated entity(DeliveryAddress),
while this code works normally within the app, or within eclipse, it breaks when run as part of a maven execution. We have integration tests which are run with maven so it fails for us. The error is this.

This same issue is reported at https://github.com/Wikidata/Wikidata-Toolkit/issues/58.
I believe a fix is also mentioned in that link.
Please fix it so that we can run our maven tests without any errors.
Thanks,
Sachin

The error is caused by a clash of dependencies as Christoph Schubert pointed out. To quote from his comment:
Both org.json:json and com.vaadin.external.google:android-json provide a org.json.JSONException. The first library has one extending RuntimeException while the latter provides a checked Exception.
The only solution I can think of is to exclude one of the two libraries in your dependency tree.
