v1.34.0

Compatibility Notes

• The methods refreshTokenGrant,userTokenGrant and clientCredentialsGrant of the xsuaa-service now accept a string or XsuaaServiceCredentials as first argument.
  In case it is a string it is treated as the URL to fetch the access token from.
  In case it is an object of type XsuaaServiceCredentials, the the URL is built by appending oauth/token to the .url of the given object.
  In the past this suffix was also appended to inputs of type string.

New Functionality

• Add experimental support for client generation of OpenAPI services. All functionality related to the OpenAPI generator is subject to change.
• Introduce ErrorWithCause for better analysis of errors, their causes and their root causes. All errors that have been caused by other errors through the SDK are based on this class.
• Support Destinations with authentication type OAuth2UserTokenExchange.

Improvements

• Unify naming of the request builder methods. See this adr for a list of the changed methods.

Fixed Issues

• Stop appending oauth/token if the service token URL is given to clientCredentialsGrant().
  See related compatibility note above.
