In SDK 2.0 some packages changed and a new jar file called commander-client.jar was introduced. Requests and responses live in commander-client.jar as of SDK 2.0. The file commander-client.jar is now shipped with CloudBees CD (CloudBees Flow) in the CloudBees CD (CloudBees Flow) InstallDir/utils directory as of CloudBees CD (CloudBees Flow) v4.2.1.
You may have to contact Electric Cloud Technical Support to get a copy of the commander-client.jar if you are not running v4.2.1 and later.
Including in classpath
For Linux, the commander-client.jar will automatically be included in the classpath.
For Windows, simply placing commander-client.jar in the utils directory may not build it into the classpath. You have to reset the COMMANDER_HOME ENV variable to C:\Program Files\Electric Cloud\ElectricCommander without quotes.
