Hi JB,
Thanks a lot for your response. I still don't understand if the type of the
setter and getter is not simple properties (String, int, long, boolean,
etc.), how should I compose the JSON argument in the command line. For
example, my Options interface is like below:
import java.util.logging.Level;
private Interface Options extends PipelineOptions {
@Description("log level")
Level getLogLevel();
void setLogLevel(Level value);
}
If I want the log level to be INFO, what JSON string should I pass to
"--logLevel=" command line argument?
Thanks,
Shen
