The blackduck-common library supplies convenient communication with a Black Duck server through REST API's as well as providing convenient ways to download the CLI and execute it. To run integration tests, create a test.properties file under src/test/resources and populate the relevant key-value pairs (See TestingPropertyKey enum for possible keys).
You can download the latest release from Maven Central.
