401:Authentication credentials were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.

I am getting 401 error, I cross-checked with keys and it works fine manually using twurl. I tried working with master branch itself and I was able to succeed with Audience creation and OAuth 1.0 works fine. I just compiled the master branch as jar, I used that jar in my project. I am facing the below issues.

Note: When I use the maven repository jar I am getting error like {"errors":[{"code":"INVALID","message":"Version 5.0 is not available."}],"request":{"params":{}}} . So I was trying the above approach.

Error Log:
TwitterTest > createAudience() FAILED
