Beam template for dataflow will not upload to bucket

I've followed all the quickstarts/documentation for creating Java-based dataflow templates. The steps I've found and done is:

1) Create the project:

mvn archetype:generate \
      -DarchetypeGroupId=org.apache.beam \
      -DarchetypeArtifactId=beam-sdks-java-maven-archetypes-examples \
      -DarchetypeVersion=2.22.0 \
      -DgroupId=com.example \
      -DartifactId=JsonToBucket \
      -Dversion="0.1" \
      -Dpackage=com.example.dataflow \
      -DinteractiveMode=false

2) mvn clean && mvn compile

This reports build success

3) Compile and upload to bucket

mvn compile exec:java -Pdataflow-runner \                      
-Dexec.mainClass=com.example.dataflow.JsonToBucket -Dexec.cleanupDaemonThreads=false  \   
-Dexec.args="--runner=DataflowRunner \
--project=PROJECT \
--stagingLocation=gs://some-bucket/staging \
--templateLocation=gs://some-bucket/beam_templates/DisruptivePubSubToBucket"

The output of this is:

No files are uploaded to the bucket set in step 3.

What could be wrong?

The issue was with the run() method. Taken from @gixen comment:

The problem was a real small thing, the run() method was never triggered
