When I tried to build the project, it failed because of unresolved dependencies.

Code change: https://github.com/suztomo/beam/pull/new/bom_offline_dependencies_plugin

1. The error implies that Gradle was trying to get artifacts listed in the BOM even when Beam does not use it. For example,

suztomo-macbookpro44% ./gradlew --offline :runners:google-cloud-dataflow-java:compileJava
Configuration on demand is an incubating feature.
