Triggers a new build of the selected BuildMaster application and sets the BUILDMASTER_BUILD_NUMBER environment variable.
The choice of using the build step or post build action to trigger a BuildMaster build will be largely dependent on how you import the build artifacts into BuildMaster:
To deploy the build to the first environment ensure that you have the post-build step action "Auto-Promote Build to the Next Environment" set in BuildMaster.
If you have multiple Jenkins jobs all triggering a build for the same BuildMaster application check out the "Enable Deployable in BuildMaster" and "Copy Previous Build's Variables" options as a means to ensure that the new BuildMaster build picks up artifacts from only the Jenkins jobs that have build for its release.
