java.util.logging.Level is not a simple type, the only way to get complex types to work is to have the appropriate annotations <https://github.com/FasterXML/jackson-annotations> on the class. Unfortunately this is a class that your not the author of, the best bet is to not use the java type but to substitute it with something that you have control over.
For example, Dataflow <https://github.com/apache/incubator-beam/blob/master/runners/google-cloud-dataflow-java/src/main/java/org/apache/beam/runners/dataflow/options/DataflowWorkerLoggingOptions.java> uses its own enum (which is a simple type) and then internally converts the representation. You could also have an enum and even choose to add methods <http://stackoverflow.com/questions/18883646/java-enum-methods> to it which can convert between your enum and java.util..logging.Level instances. If you had an enum with "ERROR", then on the command line you would specify '--logLevel=ERROR' Luke On Fri, Sep 2, 2016 at 7:17 AM, Shen Li <cs.she...@gmail.com> wrote: > Hi JB, > > Thanks a lot for your response.
