dropwizard-version-bundle

A Dropwizard bundle that exposes the version of your application as well as its dependencies via the admin port.

[] (http://travis-ci.org/dropwizard-bundles/dropwizard-version-bundle)

Getting Started

Just add this maven dependency to get started:

<dependency>
  <groupId>io.dropwizard-bundles</groupId>
  <artifactId>dropwizard-version-bundle</artifactId>
  <version>1.0.5</version>
</dependency>

Add the bundle to your environment using your choice of version supplier:

public class MyApplication extends Application<Configuration> {
  @Override
  public void initialize(Bootstrap<Configuration> bootstrap) {
    VersionSupplier supplier = new MavenVersionSupplier("<YOUR GROUP>", "<YOUR ARTIFACT ID>");
    bootstrap.addBundle(new VersionBundle(supplier));
  }

  @Override
  public void run(Configuration cfg, Environment env) throws Exception {
    // ...
  }
}

Or if you need access to your configuration in your supplier use the ConfiguredVersionBundle as follows:

public class MyApplication extends Application<Configuration> {
  @Override
  public void initialize(Bootstrap<Configuration> bootstrap) {
    bootstrap.addBundle(new ConfiguredVersionBundle<Configuration>()
    {
        @Override
        public VersionSupplier provideSupplier(Configuration configuration)
        {
            return new MyConfiguredVersionSupplier(configuration);
        }
    });
  }

  @Override
  public void run(Configuration cfg, Environment env) throws Exception {
    // ...
  }
}

Now you can access the the /version URL on the admin port of your application to see the version of your application as well as its dependencies.

For example if your application were running on localhost with the admin server on port 8081 then something like the following would show you your application's version.

curl localhost:8081/version

Customizing the version supplier

By default the bundle only comes with a single version supplier MavenVersionSupplier that will discover the version information for a particular maven artifact by reading the pom.properties file in a maven produced jar.

The VersionSupplier that plugs into the bundle is customizable however so you can define your own implementation if your needs are different. If you implement a new VersionSupplier that is generally useful for others then please feel free to submit a pull request.
