Dropwizard Debian Package

Build Status Coverage Status Maven Central

A maven plugin for packaging your Dropwizard Application as a Debian package. Your Application is managed as a SystemD, Upstart or SystemV job, with the service name ${project.artifactId}.

During packaging your configuration file is treated as a Mustache template, and configuration properties injected. Parameters are exposes prefixed with both dw and dropwizard. Missing properties will cause the build to fail. Assuming validate is set to true (the default), the configuration will be validated, and build failed if it fails.

  • Application packaged as a self contained Debian package.
  • Ensures a JRE/JDK is installed through Debian package management.
  • Generates application configuration from a Mustache template, allowing injecting values based on maven profiles.
  • Validates generated application configuration against the application itself. An invalid configuration file will cause the build to fail.
  • Once installed your application is managed as an Upstart or Systemd job.
  • Sensible default JVM options.
  • stdout, stderr and GC logging enabled by default.


Sample plugin definition in project pom


Sample Application configuration template

# {{{}}} - {{{project.description}}}
# {{{project.artifactId}}} configuration

    - type: http
      port: {{{dw.httpPort}}}
    - type: http
      port: {{{dw.httpAdminPort}}}

  level: INFO

    - type: console
    - type: file
      currentLogFilename: "{{{path.logDirectory}}}/test.log"
      archive: false


Below is the default configuration. The only required parameter is the configTemplate path, however it is highly likely you will also require some dropwizard properties to be injected in to the service configuration.
