Solution:
A build command exists which publishes BIRT content to the Cúram BIRT Viewer. This build command will only execute cleanly if an environment variable 'DEVENV' is created. This variable 'DEVENV' must point to the parent directory of the BIRT Eclipse folder.
If the eclipse install folder is named "eclipsebirt" no further action is required. Otherwise, change the property <version-eclipsebirt=eclipsebirt>, e.g. if birt eclipse is installed into directory named <BIEclipse> then update the property to <version-eclipsebirt= BIEclipse>.This property is located in the file <BIRTthird_party_version.properties> within the BIApp directory.
