There are several ways to publish data to the Black Duck Hub and the Jenkins plugin is one of them. However, there is also a Maven plugin and Gradle plugin. The latter two allow builds to continue and succeed even if the Black Duck Hub is unavailable.

However, this option has not yet made it into the Jenkins plugin. It would be nice for parity to allow builds to succeed even if Black Duck Hub is unavailable (or the data fails to upload for some other reason). At the moment the build is marked unstable if Black Duck Hub is unavailable; from one of our builds:
