When attempting to use the Conjur client I am receiving the following exception:

String value = conjur.variables().retrieveSecret("db/postgres/username");
System.out.println("THIS IS THE VALUE: " + value);

Expected Results

Retrieve a secret successfuly.

Actual Results (including error logs, if applicable)

Additional Information

[AndrewCopeland]

I was able to resolve the error above by including the following dependency in my pom.xml:

    <dependency>
      <groupId>org.glassfish.jersey.core</groupId>
      <artifactId>jersey-client</artifactId>
      <version>3.0.0-M6</version>
    </dependency>

Now I am receiving the following exception:

I also decided to include the following dependency but the exception still occurs:

    <dependency>
      <groupId>javax.ws.rs</groupId>
      <artifactId>javax.ws.rs-api</artifactId>
      <version>2.0</version>
    </dependency>

Hey @AndrewCopeland,

I also ran into issues with dependencies and tried to gather info in here: https://discuss.cyberarkcommons.org/t/conjur-and-clojure/909/5

Thanks,
