When building a jnlp with the maven-webstart-plugin, I found that the runtime dependencies weren't being included in the jnlp.

I'm using a template like this:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="$jnlpspec" codebase="${url}/${appName}" href="${outputFile}">
    <information>
        <title>${appName}</title>
        <vendor>$project.Organization.Name</vendor>
        <homepage href="${url}/${appName}"/>
        <offline-allowed/>
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="$j2seVersion"/>
        $dependencies
    </resources>
    <application-desc main-class="${main}" />
</jnlp>

How can I include the runtime dependencies? Well, I can include them all individually:

<plugin>
    <groupId>org.codehaus.mojo.webstart</groupId>
    <artifactId>webstart-maven-plugin</artifactId>
    <configuration>
      <dependencies>
        <includes>
          <include>groupId:artifactId</include>
          ...
        </includes>
      </dependencies>
      ...
    </configuration>
  </plugin>

...but ideally, I don't want to have to remember to change this every time I add a runtime dependency to my project.

Is there a way to instruct the plugin to include all runtime dependencies?

So it turns out that the default is to include all compile and runtime dependencies.

What was going on?

Well, I'm also using ant to deploy the jnlp onto a server, and in the ant file, $dependencies was being set using mvn:dependencies without the scope being specified as runtime. So adding the scope changes the $dependencies fileset which is incorporated into the jnlp file.

I use a parent pom configuration where one of the modules is the web start project. I like to keep this as minimal as possible. I have compile dependencies only to a logging library, the main application module (another module in the same parent pom structure), and jar files including native binaries. In addition to these compile dependencies, I have some test dependencies and a system dependency to a local javaws.jar file.

It seems that the maven webstart plugin includes any runtime dependencies from modules which is included to the web start project as a compile dependency. It might be a solution for you to split up your project in a similar manner.

Regarding the native binaries. I had to modify the velocity template somewhat to get these dependencies as nativelib instead of jar resources.

  • Could you share your solution with modified velocity template for nativelib parameter, please? – rauch Apr 16 '12 at 14:54
