Re: Using Constants based on Environment

Ideally your build tool should put your environment into prod or dev mode and the GWT app shouldn't know/care about it. With Maven / Gradle / Ant you can use "resource filtering" to rewrite resources like property files while being copied to the output folder. 

In that case you would have

Config.properties:

key = ${key}

dev.properties:

key = devValue

prod.properties:

key = prodValue

and the build tool will replace ${key} with the value of one of the other two files before GWT will pick up config.properties.

Otherwise you might try (no idea if it works):

interface Config extends Constants {...}

interface DevConfig extends Config {...} -> create a file DevConfig.properties

interface ProdConfig extends Config {...} -> create a file ProdConfig.properties

and in Java code

Config config;

if ("dev".equals(System.getProperty("env")) {

  config = GWT.create(DevConfig.class);

} else if ("prod".equals(......)) {

  .....

}

Can't remember, but System.getProperty() might require GWT 2.8.
