dgbuilder docker build is failing due to an issue in npm install. Unfortunately, the Jenkins log is not helpful but this issue is also seen in local builds.

To recreate issue in local build:
cd ccsdk/distribution
mvn clean install
cd ubuntu
mvn clean install -P docker -Ddocker.pull.registry=nexus3.onap.org:10001 [if behind proxy : -Ddocker.buildArg.http_proxy=$http_proxy -Ddocker.buildArg.https_proxy=$https_proxy]
cd ../dgbuilder-docker
mvn clean install -P docker
