DESCRIPTION
    Builds a flex template file from the specified parameters.

EXAMPLES
    To build and store a the flex template json file, run:

        $ gcloud dataflow flex-template build gs://template-file-gcs-path \
            --image=gcr://image-path \
            --metadata-file=/local/path/to/metadata.json --sdk-language=JAVA

    If using prebuilt template image from private registry, run:

        $ gcloud dataflow flex-template build gs://template-file-gcs-path \
            --image=private.registry.com:3000/image-path \
            --image-repository-username-secret-id="projects/test-project/sec\
        rets/username-secret" \
            --image-repository-password-secret-id="projects/test-project/sec\
        rets/password-secret/versions/latest" \
            --metadata-file=metadata.json --sdk-language=JAVA

    To build the template image and flex template json file, run:

        $ gcloud dataflow flex-template build gs://template-file-gcs-path \
            --image-gcr-path=gcr://path-to-store-image \
            --jar=path/to/pipeline.jar --jar=path/to/dependency.jar \
            --env=FLEX_TEMPLATE_JAVA_MAIN_CLASS=classpath \
            --flex-template-base-image=JAVA11 \
            --metadata-file=/local/path/to/metadata.json --sdk-language=JAVA
