Maven Recipe: Delivering applications as RPMs

In the Java world, the standard unit of delivery is the jar/war/(x)ar file. For applications which don’t fit the ‘single file’ delivery model, there is no standard alternative.  To provide a solution, I will show you how to package your application with Maven as an RPM.

As we are talking about Maven, the solution starts with finding the right plugin – in our situation the rpm-maven-plugin. We include the plugin as follows:


The goal we need to execute is rpm – and it attaches itself to the package phase by default – so far so good.

The configuration that is usually done in a RPM spec file is done inside the plugin’s configuration block. First, we list some required descriptive elements:

  <copyright>2010, NoBody</copyright>
  <description>Maven Recipe: RPM Package.</description>

Now we get to the core of the RPM – listing the files to deploy. As we want to deploy our application’s classes and the ones from our dependencies, we create a mapping:


This is a very compact way of declaring that we want all dependencies – the dependency tag – and our primary build artifact – the artifact tag – to be deployed to the lib directory of our application.

The next step is to take the file which is checked into source control and deploy it as a sample file in the conf directory, so that we have a reference at hand when configuring the application:


Using location and destination we have absolute control over what is included and where it is placed. Also note the usage of the configuration tag, which translates in to the %config RPM macro, which means that changes to the file are preserved when updating or removing RPM  ( details on the RPM %config macro ).

Last, we need to generate an empty logs directory for our application. This is done simply by declaring a mapping with no sources.


Right now we can build a RPM out of our application. I’ve added hibernate 3.3.2.GA as a dependency, since it brings in a few transitive dependencies.

Let’s verify that the RPM file indeed contains all that we asked it to:

robert@neghvar:~/workspace/rpm-package> rpm -qlp /home/robert/workspace/rpm-package/target/rpm/rpm-package/RPMS/rpm-package-0.0.1-SNAPSHOT20100520205409.noarch.rpm

We have reached our goal of building an RPM with our applications dependencies, classes and configuration files. By using the rpm-maven-plugin we have managed to keep using Maven as our build tool interface, and also reused the information available in the POM file for declaring dependencies.
