Problem with setting port on command line

According to SimpleServerFactory docs:

A startup script can override the port via {@code -Ddw.server.connector.port=$PORT}.

However, when I try:

java -Ddw.server.connector.port=8081 -jar my.jar server config.yml

I get:

config.yml has an error: Failed to parse configuration at: server.connector; Unexpected token (END_OBJECT), expected FIELD_NAME: missing property ‘type’ that is to contain type id (for class io.dropwizard.jetty.ConnectorFactory) at [Source: N/A; line: -1, column: -1](through reference chain: com.acmerocket.stratum.StratumConfiguration[“server”]->io.dropwizard.server.SimpleServerFactory[“connector”])

Without -Ddw.server.connector.port=8081, the app comes up fine.

I was able to get it working like this :

java -Ddw.server.applicationConnectors\[0\].type="http" -Ddw.server.applicationConnectors\[0\].port="8080" -jar target/<UR_JAR>.jar server conf.yml

Dropwizard Version:

<dropwizard.version>1.3.8</dropwizard.version>

The PR #866 does not seem to fix this problem here (tried dropwizard version 1.3.12). I.e. you have to specify a config.yml with at least:

server:
  applicationConnectors:
   - type: http

in order to change the port. Otherwise you’ll get:

IllegalArgumentException: Unable to override server.applicationConnectors[0].type; node with index not found
